The fake “Threat Detected: xxbc Detected” pop-up scam is a prevalent tech support scam affecting Windows and Mac users alike. This fraudulent pop-up alert claims your device is infected, your data compromised, and that you must contact tech support immediately. However, the pop-up is entirely fake, designed to trick unsuspecting users into handing over money and sensitive information.
In this detailed article, we will uncover everything you need to know about this scam, including how it works, what to do if you are a victim, and how to protect yourself moving forward. Forearmed with knowledge, you can avoid this scam and safeguard your data.
Overview of the Fake “Threat Detected” Pop-up Scam
The fake “Threat Detected: xxbc Detected” scam commonly appears as a full-screen pop-up alert when browsing the web. It may show on shady websites, through malvertising, malicious browser extensions, or adware/spyware.
The pop-up uses alarming language stating your system is infected, data compromised, and that you must contact tech support immediately to remove the threat. Various telephone numbers are provided, typically with 833, 844, 855, 866, 877, 888, and 877 area codes.
These numbers connect to fraudulent call centers, where scammers pose as Microsoft, Apple, or Google tech support. Their aim is to trick you into paying for useless services, expensive software, and long-term bogus support packages. At worst, they will gain remote access to your device to steal financial information.
This scam prevails because the pop-ups seem legitimate at first glance, using corporate logos and spoofing caller IDs. However, Microsoft, Apple, and Google do not use unsolicited pop-up alerts to contact users. The scam capitalizes on fear to manipulate users into calling.
Anatomy of the Fake Pop-Up
The fake pop-ups use similarly alarming language, but come in several variants targeting Windows and Mac users.
Windows Variants
Some examples read:
“Windows Defender Alert. Threat Detected: xxbc Detected. Contact Microsoft Support Immediately.”
“Windows Firewall Warning. Hacking Attempt Detected. Call Microsoft Support Now to Prevent Data Loss.”
“ALERT! Your Windows OS is infected with 5 Viruses. Call Toll-Free Number for immediate removal of viruses.”
These Windows versions use Microsoft or Windows branding to appear legitimate. The pop-ups are designed to look like real Windows security alerts.
Mac Variants
Mac versions may state:
“MacOS Security Alert. Your system is infected with Privacy Threats. Call Apple Support now to remove threats.”
“MacOS Firewall Warning. Malware Detected. Contact Apple Support Immediately to Prevent Data Loss.”
“URGENT Warning for Mac Users. Malicious Threats Detected. Call Apple Support Now.”
These variants exploit trust in the Apple brand. Some even mention specific malware like “MacKeeper” or “MacDefender.”
Common Tactics
All versions use technical jargon like “Firewall,” “Malware,” “Viruses,” and “Threats” to sound convincing. They warn your data is in danger to create urgency. The only solution offered is to call tech support, with phone numbers prominently displayed.
Some versions even prevent you exiting the page, forcing you to call the number. The scammers exploit fear and limited technical knowledge to trick users.
How the Scam Works Step-by-Step
Now let’s explore exactly how the fake pop-up scam operates at each stage:
1. Fake Pop-up Displayed
The first step is the pop-up appearing on your screen while browsing the web. This usually happens when visiting shady websites, often through:
- Malvertising – Fake ads containing malware.
- Compromised Sites – Hacked sites that plant pop-ups.
- Rogue Extensions – Browser add-ons containing adware.
- Software Bundles – Free software hiding unwanted programs.
Pop-ups may also appear via push notifications on mobile devices. The scam relies on stealthy methods to display pop-ups without your permission.
2. Pop-up Spoofs Legitimate Alert
The pop-up is designed to mimic a real alert from Microsoft, Apple, or Google. It will contain corporate logos, use technical language, and claim your system is compromised.
On Windows, it pretends to be Windows Security, Defender, or Firewall. On Mac, it impersonates MacOS Security alerts. The scare tactics aim to trick you into thinking the alert is authentic.
3. Pop-up Says to Call Tech Support
After claiming your system is infected or hacked, the pop-up insists you call tech support immediately. Phone numbers with 833, 844, 855, 866, 877, and 888 area codes are prominently displayed.
These numbers appear trustworthy, often spoofing Caller ID so that Microsoft, Apple, or Google appears on your phone when they call back. However, the numbers connect to fraudulent call centers.
4. Fake Tech Support Performs Diagnosis
If you call the number, scammers will pose as Microsoft, Apple, or Google support technicians. They will ask some questions to “diagnose” the problem, but quickly state your system is compromised.
These fake diagnoses are designed to scare you into believing there is a serious security threat that only they can fix.
5. Scammers Offer to Remove Threat for a Fee
Next, the scammers will offer to remove the non-existent threats and infections for an exorbitant fee. Common scams include:
- Charging $200+ for long-term “security packages”.
- Selling you useless anti-virus software for $499.
- Tricking you into paying $500+ to “renew” your license key.
They may even gain remote access to your device under the guise of removing infections. Remote access allows them to steal personal data and install more malware.
6. Further Social Engineering Tactics
If you seem hesitant, the scammers may use various manipulation tactics to coax you into complying:
- Pressuring and rushing you into making a decision.
- Citing limited-time offers to act now.
- Pretending to be transferring you to a manager to negotiate a better deal.
- Passing you between multiple scammers to verify the threat.
Their social engineering techniques exploit confusion, doubt, and anxiety to eventually wear you down.
7. Scammers Request Remote Access
A common tactic is convincing you to download remote access software like AnyDesk so they can “remove infections.” This allows them to control your computer unsupervised.
They may install more malware, steal passwords stored on your system, access financial information, and hold your device for ransom. Remotely accessing your device provides the scammers unfettered control to rob you blind.
8. Scammers Steal your Money
Ultimately, the scammers leverage the fabricated threats to steal your money. Common targets include:
- Bank account details and online banking passwords.
- Credit card numbers.
- Remote access to financial accounts.
- Getting you to purchase gift cards and provide the redemption codes.
- Installing ransomware and extorting you for money to regain computer access.
The pop-up is just an entry point to manipulate you and gain access to your sensitive information. Avoid calling the number at all costs.
What to Do If You Are a Victim of This Scam
If you fell victim and called the number, don’t panic. Here are important steps to protect yourself now:
Disconnect from the Scammers Immediately
First and foremost, end the call with the scammers. Make an excuse that you need to discuss this with your family and hang up. The longer you stay on the call, the more opportunity they have to manipulate and socially engineer you.
Reset All Account Passwords
Assume your passwords and financial information is compromised. Change passwords for online banking, email, social media, and any other sensitive accounts. Enable two-factor authentication wherever possible for additional protection.
Check Bank Accounts for Fraudulent Activity
Closely monitor bank accounts and credit cards used on your device for suspicious charges. Report any fraudulent transactions to your bank immediately. Consider freezing accounts as a precaution until you regain control.
Run Security Scans to Remove Malware
If you granted the scammers remote access, save and scan your device with legit antivirus software like Malwarebytes to remove any potential infections. Also change all account passwords from another clean device to be safe.
Inform Relevant Institutions of the Breach
Notify your bank, credit card providers, identity protection services, and any other impacted institutions. They can take precautions, issue new cards, and alert you of suspicious activity. The sooner they are informed, the better.
Block Associated Phone Numbers
Block all phone numbers the scammers called you from. If they called using spoofed numbers, block the numbers displayed in the pop-up alert. This prevents further calls trying the same technique.
Report the Scam
File a complaint with the FTC at ReportFraud.ftc.gov and notify your local authorities. Provide all details to help authorities stop these operations. Also report the pop-up to Google or Microsoft if their logos were misused.
By taking these steps, you can contain the damage and prevent the scammers from further accessing your accounts and identity. Act quickly to protect yourself in the aftermath.

With the malicious programs removed, you’re ready for the next step in this guide.
STEP 2: Reset browsers back to default settings
In this step, we will remove spam notifications, malicious extensions, and change to default any settings that might have been changed by malware.
Please note that a Chrome or Edge reset turns off all your extensions, and a Firefox refresh removes them. Your bookmarks and favorites stay intact. For each browser that you have installed on your computer, please click on the browsers tab below and follow the displayed steps to reset that browser.
Reset Chrome for Windows to default settings
We will now reset your Chrome browser settings to their original defaults. This will reset your startup page, new tab page, search engine, and pinned tabs. It will also disable all extensions and clear temporary data like cookies. Your favorites, history, and saved passwords will not be cleared.
Open the Chrome menu
Open Google Chrome and click the three-dot (⋮) icon in the top-right corner.
Open Chrome Settings
Select Settings from the Chrome menu.
Select “Reset settings”
Look at the menu on the left side of the Settings page. Scroll down and click Reset settings.
Restore Chrome’s original settings
Click Restore settings to their original defaults.
Confirm the Chrome reset
A confirmation window will appear. Click Reset settings.
This will:
- Restore the default search engine, homepage, and new tab page
- Reset startup pages and pinned tabs
- Reset site permissions, such as notifications and pop-ups
- Disable installed extensions
- Clear temporary cookies and website data
Don’t worry: Chrome will not delete your bookmarks, browsing history, or saved passwords. If you’re signed in to Chrome, the reset applies on all devices where you’re signed in.
Restart Chrome and perform a test search. If your searches now open normally in Google, you can stop here.
If searches are still redirected through shady domains complete the additional step below.
Remove persistent search hijacker data
Only complete this step if the redirect continues after resetting Chrome.
Some browser hijackers hide inside Chrome’s local search-engine database. A standard Chrome reset may not remove this database, which is why searches can continue to pass through shady sites.
The following procedure creates a backup of the affected database and allows Chrome to build a new, clean version. This is safer and less disruptive than deleting the entire Chrome profile.
First, prevent Chrome Sync from restoring the hijacked settings:
- Open a new Chrome tab.
- Copy the following address, paste it into Chrome’s address bar, and press Enter:
chrome://settings/syncSetup/advanced - Under Manage what you sync, select Customize sync.
- Turn off Settings and Extensions.
- You can leave Bookmarks and Passwords enabled so your important data remains synchronized.
Note: Some newer Chrome versions may automatically redirect this address to the Google Account settings page. If that happens, locate the list of synchronized Chrome data and turn off Settings and Extensions there.
Now save anything you are working on and close every Chrome window.
Run the cleanup command:
- Press the Windows key on your keyboard.
- Type PowerShell.
- Open Windows PowerShell. Administrator access is not required.
- Copy the entire command shown below.
- Right-click inside the PowerShell window to paste the command, then press Enter.
- If Windows warns you about pasting multiple lines, select the option to continue.
$stamp = Get-Date -Format "yyyyMMdd-HHmmss"
Get-Process chrome -ErrorAction SilentlyContinue |
Stop-Process -Force
$root = "$env:LOCALAPPDATA\Google\Chrome\User Data"
if (Test-Path $root) {
$profiles = Get-ChildItem $root -Directory |
Where-Object {
$_.Name -eq "Default" -or
$_.Name -match "^Profile \d+$"
}
foreach ($profile in $profiles) {
foreach ($name in @(
"Web Data",
"Web Data-journal",
"Web Data-wal",
"Web Data-shm"
)) {
$file = Join-Path $profile.FullName $name
if (Test-Path $file) {
$backup = "$file.search-hijacker-backup-$stamp"
Move-Item -LiteralPath $file -Destination $backup
Write-Host "Backup created: $backup"
}
}
}
}
Write-Host ""
Write-Host "Chrome search data has been cleaned."
Write-Host "You can now reopen Chrome."Wait until PowerShell displays the following message:
Chrome search data has been cleaned.
You can now reopen Chrome.
Close PowerShell and reopen Google Chrome. Chrome will automatically create a clean search database for every local profile.
Next, copy the following address, paste it into Chrome’s address bar, and press Enter:
chrome://settings/searchEngines
Make sure Google is selected as the default search engine. Test several searches from the address bar and confirm that they no longer pass through shady search engines.
Your important Chrome data is protected: the PowerShell cleanup does not remove bookmarks, saved passwords, browsing history, cookies, or installed extensions. However, it may reset locally stored Autofill addresses, payment cards saved only on this computer, and form suggestions.
The original search database is not deleted. PowerShell renames it and adds
search-hijacker-backupto its filename so it can be recovered if necessary.Keep Settings and Extensions synchronization disabled while testing Chrome. Do not enable every extension at once. Enable only the extensions you recognize, one at a time, and test Chrome after each one.
If the redirect returns after enabling a particular extension, remove that extension immediately.
Reset Firefox for Windows to default settings
We will now reset your Firefox browser settings to their default. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history, and open tabs.
-
Open the Firefox menu and click “Help and Report”
Click the three horizontal lines in the top-right corner of Firefox to open the main menu, then select “Help and Report“.
-
Click “More troubleshooting information”
In the Help and Report menu, click “More troubleshooting information“.
-
Click “Refresh Firefox”
On the “Troubleshooting Information” page, click the “Refresh Firefox” button in the “Give Firefox a tune up” box in the top-right area of the page.
-
Confirm the refresh
In the confirmation window, click “Refresh Firefox” again. This removes extensions, themes, and customized settings — the usual hiding places for browser hijackers — while keeping your bookmarks, history, and saved passwords safe.
-
Click “Finish”
Firefox will close, reset itself to default settings, and reopen with a window listing the information that was restored. Click “Finish“. Then test Firefox before you add back any extensions.
About the “Old Firefox Data” folder: Firefox saves a copy of your old profile on your desktop. If something you need is missing after the reset, you can recover it from this folder. Otherwise, delete the folder — it contains sensitive data like passwords and cookies, and may also still hold the malicious files you just removed.
Reset Microsoft Edge to default settings
We will now reset your Microsoft Edge browser settings to their default. This will reset your startup page, new tab page, search engine, and pinned tabs. It will also disable all extensions and clear temporary data like cookies. Your favorites, history, and saved passwords will not be cleared.
Updated for Microsoft Edge on Windows 10 and Windows 11 — July 2026.
-
Open the Edge menu and click “Settings”
Open Microsoft Edge. In the top-right corner, click the three-dot (…) icon, then click Settings.
-
Prevent the unwanted settings from returning through Edge Sync
If you are signed in to Microsoft Edge, a bad setting or extension may be stored in your Microsoft account and return after the reset.
Copy the following address, paste it into the Edge address bar, and press Enter:
edge://settings/profiles/syncOn the Sync page, turn off these two options:
- Settings
- Extensions
You can leave Favorites and Passwords turned on.
If Edge says that sync is already off, simply continue to the next step.
Important: Edge Sync settings are separate for each profile. If you use more than one Edge profile, switch to each affected profile and repeat this step.
You do not need to sign out of your Microsoft account or delete the Edge profile.
-
Open “Reset settings”
In the left sidebar, click Reset settings.
You can also open the reset page directly. Copy the following address, paste it into the Edge address bar, and press Enter:
edge://settings/reset
-
Click “Restore settings to their default values”
Click Restore settings to their default values.
-
Confirm the reset
In the confirmation dialog, click Reset.
This resets the startup page, new tab page, search engine, and pinned tabs. It also disables all extensions and clears temporary site data, such as cookies.
Don’t worry: your favorites, browsing history, and saved passwords will not be deleted.
-
Check your extensions before turning them back on
Copy the following address, paste it into the Edge address bar, and press Enter:
edge://extensionsRemove any extension you do not recognize or no longer use. Pay particular attention to extensions related to search, coupons, shopping, PDF conversion, browser protection, new tabs, or video downloading.
Do not turn all extensions back on at the same time. Enable only the extensions you recognize and trust.
-
Select a trusted search engine
Copy the following address, paste it into the Edge address bar, and press Enter:
edge://settings/searchEnginesSelect Bing, Google, DuckDuckGo, or another search provider you trust and make it the default. This address opens the list of search engines; the default is set one page back, on Address bar and search, under Search engine used in the address bar.
Remove any unknown search engines from the list, especially providers with strange names or addresses that you did not add yourself: click More actions (…) next to the engine and remove it.
Restart Edge and perform a search from the address bar. If searches are no longer redirected, you can stop here.
-
If the redirect remains, clean the corrupted search data without deleting the Edge profile
Use this additional step only if Edge continues to redirect searches after the normal reset.
This command cleans the search-engine database from every local Edge profile while keeping your favorites, saved passwords, browsing history, cookies, and profiles.
Before continuing: save anything you are working on because the command will close Microsoft Edge.
- Open the Windows Start menu.
- Type PowerShell.
- Open Windows PowerShell. Administrator access is not required.
- Copy the entire command below.
- Paste it into PowerShell and press Enter.
$stamp = Get-Date -Format "yyyyMMdd-HHmmss" $root = Join-Path $env:LOCALAPPDATA "Microsoft\Edge\User Data" Get-Process -Name msedge -ErrorAction SilentlyContinue | Stop-Process -Force -ErrorAction SilentlyContinue Start-Sleep -Seconds 2 if (-not (Test-Path -LiteralPath $root)) { Write-Host "The Microsoft Edge profile folder was not found:" Write-Host $root return } $profiles = Get-ChildItem -LiteralPath $root -Directory | Where-Object { $_.Name -eq "Default" -or $_.Name -match "^Profile \d+$" } $movedFiles = 0 foreach ($profile in $profiles) { foreach ($name in @( "Web Data", "Web Data-journal", "Web Data-wal", "Web Data-shm" )) { $file = Join-Path $profile.FullName $name if (Test-Path -LiteralPath $file) { $backup = "$file.search-reset-backup-$stamp" try { Move-Item -LiteralPath $file -Destination $backup -ErrorAction Stop Write-Host "Cleaned: $($profile.Name)\$name" $movedFiles++ } catch { Write-Warning "Could not clean: $file" } } } } Write-Host "" if ($movedFiles -gt 0) { Write-Host "Microsoft Edge search data has been cleaned." -ForegroundColor Green Write-Host "You can now reopen Microsoft Edge." } else { Write-Host "No Edge search database files were found." -ForegroundColor Yellow }The command does not permanently delete the original files. It renames them as backup files, and Edge creates a clean search database when it starts again.
Note: this additional cleanup may also reset saved form-fill suggestions, saved addresses, payment cards saved only on this computer, and manually added search engines. It does not delete favorites, passwords, or browsing history.
-
Reopen Edge and test the browser
Open Microsoft Edge again, visit edge://settings/searchEngines, and select your preferred search engine (one page back, on Address bar and search, under Search engine used in the address bar).
Perform several searches from the address bar to confirm that the redirect is gone.
Keep synchronization for Settings and Extensions turned off until you are certain that the computer and extensions are clean. If you enable them again, turn them on one at a time and test Edge after each change.
-
If Edge still redirects your searches
Open edge://policy. If this is your personal computer and Edge displays unknown policies such as ExtensionInstallForcelist or DefaultSearchProvider, the hijacker may be installed outside the browser profile.
In that situation, continue with the next malware-removal steps and run a complete antivirus scan. If the computer belongs to a company or school, contact its IT administrator before changing any policies.
STEP 3: Use Malwarebytes Anti-Malware to remove malware and unwanted programs
In this third step, we will install Malwarebytes to scan and remove any infections, adware, or potentially unwanted programs that may be present on your computer.
Malwarebytes is one of the most popular and trusted anti-malware tools for Windows — and it’s completely free for removing infections. It catches threats that many antivirus programs miss, including adware, browser hijackers, and trojans. Follow the steps below to scan your PC and remove what Malwarebytes finds.

Optional: Check for rootkits with a Custom Scan
You don’t need to change any settings for a normal scan. The standard Threat Scan in the next step is enough for most problems, so you can go straight to it.
If you also want to check for rootkits, use a Custom Scan. In current versions of Malwarebytes, rootkit scanning is only available there:
- On the Scanner tile, click the three-dot menu and select Advanced Scan.
- Choose Custom Scan. In its options, check Scan for rootkits.
- Select your system drive (usually C:\) as the location to scan, then start the scan. It takes longer than a Threat Scan.
- When it finishes, review and quarantine the results as described in the steps below.
Rootkit scanning isn’t available on Windows devices with ARM processors.
Start the Scan
Click the blue Scan button. Malwarebytes will automatically update its virus database and start checking your computer for malware.
-
Wait for the Scan to Finish
The scan checks your entire system for browser hijackers and other malicious programs, so it can take 5 to 20 minutes depending on your computer. Feel free to do something else — just check back occasionally to see the progress.
-
Quarantine the Detected Threats
When the scan is done, you’ll see a list of everything Malwarebytes found — malware, adware, and potentially unwanted programs. Click the “Quarantine” button to remove all of them at once.
Malwarebytes will now remove the malicious files and registry entries and move them safely into quarantine.
-
Restart Your Computer
Some threats can only be fully removed after a reboot. If Malwarebytes asks you to restart, click Yes. Once you’re logged back in, Malwarebytes has finished removing the threats it found.
STEP 4: Use HitmanPro to scan your computer for badware
In this next step, we will scan the computer with HitmanPro to check for any other malicious programs that may be installed on your device.
HitmanPro is a second-opinion scanner — it’s designed to catch what your main antivirus might have missed. Instead of relying on a single detection engine, it checks the behavior of files in the locations where malware usually hides. Anything suspicious is checked online, where it’s analyzed by several antivirus engines in HitmanPro’s Scan Cloud.
Good news: scanning is completely free, with no limits. You only need a license when it’s time to remove what was found — and even then, you can activate a free one-time 30-day trial to remove what it finds at no cost. The trial works once per computer. After that, removal needs a paid license, and the purchase screen shows the current price.

When the removal is complete, HitmanPro will show a summary of everything it cleaned. Click Next, then click Reboot if prompted. If there’s no reboot prompt, click Close. Then check whether the problems you noticed have stopped. If they come back, save the HitmanPro log and ask for help in our forum.
STEP 5: Use AdwCleaner to remove adware and malicious browser policies
In this final step, we will use AdwCleaner to remove the malicious browser policies that were set by browser hijackers on your computer and delete malicious browser extensions.
AdwCleaner is a free on-demand scanner that specializes in adware, browser hijackers, and unwanted toolbars — the exact threats that mainstream antivirus programs often miss. It also includes tools that repair the damage malware leaves behind, like hijacked browser settings and malicious policies. It’s a quick scan that’s well worth running.
-

If Windows asks whether you want to allow AdwCleaner to run, click “Yes“. When the license agreement appears, click I agree to continue.
-
Leave “Reset Chrome policies” off unless you need it
AdwCleaner can reset Chrome policies, the settings that malware sometimes uses to lock your browser so you can’t change it back. This option removes every Chrome policy, including legitimate ones set by an employer, a school, or parental-control software, so leave it off for a normal scan.
AdwCleaner applies this option only if you run Basic Repair at the end of the cleanup. Malwarebytes advises running Basic Repair only when a support agent asks you to, and it also runs every other repair action that is turned on in the same list. If this is your own personal PC and chrome://policy in Chrome lists policies you didn’t set, ask for help in our forum instead. On a work or school computer, ask the IT administrator.
-
Start the Scan
Click “Dashboard” on the left side of the window, then click the “Scan Now” button.
-
Wait for the Scan to Finish
AdwCleaner will now check your computer for adware and other malware. This usually takes only a few minutes — it’s one of the fastest scanners around.
-
Quarantine the Detected Threats
When the scan finishes, AdwCleaner lists everything it found. Review the list and uncheck any program you installed on purpose and want to keep, then click Next. If AdwCleaner also found preinstalled software, it shows that list next. Review it the same way, then click “Quarantine“. Older versions show the Quarantine button on the first list, as in the image below.
-
Click “Continue” to Finish the Cleanup
Save any open work first — AdwCleaner needs to close your open programs before it can clean. When you’re ready, click the “Continue” button.
AdwCleaner will now move the selected items to quarantine. If it asks you to restart your PC, allow it. When you’re back in Windows, AdwCleaner may offer a Basic Repair. Click Skip Basic Repair. Malwarebytes recommends running Basic Repair only when a support agent asks you to. Then check whether the problems you noticed have stopped.
When you’ve finished these steps, check whether the problems you noticed have stopped. If they continue, see the options below.
If you are still having problems with your computer after completing these instructions, then please follow one of the steps:

- STEP 3: Reset browsers back to default settings
- STEP 4: Run a scan with Malwarebytes for Mac to remove malware
STEP 1: Remove malicious profiles
Profiles are used by IT admins in businesses to control the behavior of their Macs. These profiles can configure a Mac to do many different things, some of which are not otherwise possible.
When it comes to home users, adware and browser hijackers are using the configuration profile to prevent users from removing malicious programs from the computer. This also prevents the user from changing that behavior in the browser’s settings.
In this first step, we will check your computer to see if any configuration profiles are installed. To do this, follow the below steps:
-
Open “System Settings”
From the Apple menu () in the top-left corner of the screen, select System Settings. (On macOS Monterey and earlier, this is called System Preferences.)
-
Look for “Profiles”
Where you find configuration profiles depends on your version of macOS:
macOS Sequoia (15) and later: click General in the sidebar, then click Device Management. You may need to scroll down.
macOS Ventura (13) and Sonoma (14): click Privacy & Security in the sidebar, then click Profiles near the bottom.
macOS Monterey (12) and earlier: in System Preferences, click Profiles.
You can also type “Profiles” in the search box.
No profiles listed, or no Profiles section at all? That means no configuration profiles are installed on your Mac, which is completely normal. Skip ahead to the next step of this guide. -
Remove the malicious profiles
Malware uses configuration profiles to lock your browser settings — forcing a fake search engine or homepage on you and preventing you from changing it back. If you see a profile you don’t recognize (and your Mac isn’t managed by your workplace or school), select it, press the − (minus) button, and click Remove to confirm.
STEP 2: Delete malicious apps
In this second step, we will try to identify and remove any malicious apps and files that might be installed on your computer. Sometimes redirects or adware programs can have usable Uninstall entries that can be used to remove these programs.
-
Quit the malicious programs
Check the Apple menu bar in the top-right corner of your screen. If you see an icon you don’t recognize, click it and select Quit. This stops the malware from running so it can’t interfere while we remove it.
-
Open “Finder”
Click the Finder icon in your dock.
-
Click on “Applications”
In the Finder sidebar, click “Applications“.
-
Find and remove the malicious app
Scroll through the list of installed apps and look for anything suspicious — an app you don’t remember installing, or one with a strange or generic name. When you find it, right-click it and select “Move to Trash“.
Some known malicious programs to look for: SearchMine, TakeFresh, TopResults, FeedBack, ApplicationEvents, GeneralOpen, PowerLog, MessengerNow, ImagePrime, GeneralNetSearch, Reading Cursors, GlobalTechSearch, PDFOnline-express, See Scenic Elf, MatchKnowledge, Easy Speedtest, and WebDiscover. The names change constantly, though — so treat any app you can’t account for as suspect.
-
Empty the Trash
Before you empty the Trash, check that it doesn’t hold anything else you want to keep, because emptying it permanently deletes everything in it. Then right-click the Trash icon in your dock and select “Empty Trash“.
Check login items and background apps
Malware often sets itself to start automatically. Open the Apple menu > System Settings, click General, then click Login Items & Extensions (called Login Items in macOS Ventura and Sonoma). Look for apps you don’t recognize in the list of items that open at login and in the list of apps allowed to run in the background. Select an unwanted item and click the Remove (−) button, or turn off its switch.
This check doesn’t delete any files. Note the names you find, because they help you spot related files in the next step.
Find and remove the malicious files
Malware on Mac uses launch agents and launch daemons — small files that automatically restart the malware every time you boot your Mac. We’ll check the four folders where they hide:
- Click the desktop to make sure you’re in Finder, then open the “Go” menu and click “Go to Folder“.
- Copy and paste each of the paths below into the window, one at a time, then double-click the matching folder that appears:
- /Library/LaunchAgents
- ~/Library/LaunchAgents
- /Library/Application Support
- /Library/LaunchDaemons
- In each folder, look for suspicious .plist files — typically named after the malware or with odd, random-looking names. Examples seen in past infections include “installmac.AppRemoval.plist”, “myppes.download.plist”, “mykotlerino.ltvbit.plist”, and “com.myppes.net-preferences.plist”. A name alone is not proof. For example, “com.adobe.fpsaud.plist” belongs to Adobe’s own Flash Player updater. When you find a malicious file, move it to the Trash — then empty the Trash again when you’re done.
Be careful: these folders also contain files belonging to legitimate apps — especially /Library/Application Support, where programs like Adobe, Google, and Microsoft store their data. Only delete files you’re confident are malicious. If you’re unsure about a file, search its exact name online first, or leave it in place and continue with the Malwarebytes scan later in this guide.
- Click the desktop to make sure you’re in Finder, then open the “Go” menu and click “Go to Folder“.
STEP 3: Reset browsers back to default settings
In this third step, we will remove spam push notifications and malicious extensions, and change to default any settings that might have been changed by malware.
For each browser that you have installed on your computer, please click on the tab below and follow the displayed steps to reset that browser.
Remove malicious extensions and settings from Safari
To remove malware from Safari we will check if there are any malicious extensions installed on your browser and what settings have been changed by this malicious program.
-
Go to Safari’s “Settings”.
On the menu bar, click the “Safari” menu and select “Settings”. In older versions of Safari, this menu item is called “Preferences”.
-
Check Homepage.
This will open a new window with your Safari settings, opened to the “General” tab. Some browser hijackers may change your default homepage, so in the Homepage field make sure it’s a web page you want to use as your start-up page.
-
Click “Extensions”
Next, click on the “Extensions” tab.
-
Find and uninstall malicious extensions.
The “Extensions” screen will be displayed with a list of all the extensions installed on Safari. Look out for any suspicious browser extension that could be behind all the drama – anything you don’t remember downloading or that doesn’t sound like a genuine extension. By default, there are no extensions installed on Safari so it’s safe to remove an extension
-
Remove spam notifications ads
In Safari’s settings, click Websites, then click Notifications. Find the website that sends the spam notifications, then choose Deny from the menu next to it.
To stop other websites from asking, you can also deselect “Allow websites to ask for permission to send notifications“. This only blocks new requests. It doesn’t turn off websites you already allowed, so deny those websites as well.
You can also turn off a website’s notifications in System Settings > Notifications. Under Application Notifications, click the website and turn off Allow Notifications.
-
Remove the data stored by the unwanted website.
In the Safari menu, choose “Settings…”, select “Privacy” at the top of the new window that appears, and then click the “Manage Website Data” button.
In the next dialog box, search for or select the website that showed the spam or redirects, then click “Remove“. Click Done when you’re finished.
Avoid “Remove All” unless you really need it. It deletes the data of every website and can sign you out of all of them.
-
Empty Safari Caches.
From your Safari menu bar, click Safari and select Settings, then select the Advanced tab. Enable the checkbox “Show features for web developers“. In older versions of Safari, this checkbox is called “Show Develop menu in menu bar”.
From the menu bar select Develop, then click on Empty Caches as seen in the image below.
Remove malware from Chrome for Mac
To remove malware from Chrome for Mac we will reset the browser settings to their defaults. This restores the default search engine, homepage, new tab page, and pinned tabs. It also resets site permissions, clears cookies and site data, and turns off your extensions and themes. Your bookmarks and saved passwords are not deleted. If you’re signed in to Chrome, the reset applies on all devices where you’re signed in.
-
Click on the three dots at the top right and go to Settings.
Click on Chrome’s main menu button, represented by three dots at the top right corner. Now click on the menu option labeled Settings, which will open the basic settings screen, as shown by the numbered box in the picture below.
-
In the left sidebar, click on the “Reset settings” option.
In the left sidebar, click on “Reset settings“.
-
Click “Restore settings to their original defaults”.
Now click on “Restore settings to their original defaults” as shown in the image below.
-
Click “Reset settings” button.
A confirmation dialog should now be displayed, detailing the components that will be restored to their default state should you continue with the reset process. To complete the restoration process, click on the “Reset settings” button.
-
(Optional) Stop sync from bringing the problem back.
If a malicious extension or setting comes back after the reset, Chrome sync may be restoring it from your Google Account. Open Chrome Settings > You and Google. If you see Sync and Google services > Manage what you sync, choose Customize sync and turn off Settings and Extensions. In newer versions of Chrome, click your account name, then Choose what to save in your Google Account, and turn off the same two items. Then remove the unwanted extension again.Don’t use the “Delete data” or “Clear data” option on your Google Account’s Chrome data page to fix this. It deletes the Chrome data saved in your Google Account, such as synced bookmarks, passwords, and history, and you don’t need it to remove an extension.
Remove malware from Firefox for Mac
To remove malware from Firefox for Mac we will reset the browser settings to its default. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history, and open tabs.
-
Go to the “Help and Report” menu.
Click on Firefox’s main menu button, represented by three horizontal lines. When the drop-down menu appears, select the option labeled “Help and Report“.
-
Click “More troubleshooting information”.
Next click on the “More troubleshooting information” option. This opens the Troubleshooting Information page, as shown by the numbered box in the image below. You can also open it by typing about:support in the address bar.
-
Click on “Refresh Firefox”
Click the “Refresh Firefox” button in the “Give Firefox a tune up” box in the upper-right corner of the “Troubleshooting Information” page.
-
Confirm.
To continue, click on the “Refresh Firefox” button in the new confirmation window that opens.
-
Click on “Finish”.
Firefox will close itself and will revert to its default settings. When it’s done, a window will list the information that was imported. Click on the “Finish“.
STEP 4: Run a scan with Malwarebytes for Mac to remove malware
In this final step, we will scan the computer with Malwarebytes for Mac to find and remove any malicious programs that might be installed on your Mac.

Remove Unwanted Apps and Malware from Android
- STEP 1: Uninstall malicious apps
- STEP 2: Stop spam notifications and redirects in your browser
- STEP 3: Use Malwarebytes for Android to remove malicious apps
STEP 1: Uninstall malicious apps
In this first step, we will check if any malicious apps are installed on your phone. Sometimes browser hijackers or adware apps can have usable Uninstall entries that can be used to remove these apps.
-
Open the “Settings” menu.
Tap on the “Settings” app from your phone menu or home screen.
-
Tap on “Apps”.
When the “Settings” menu opens, tap on “Apps” to see all the installed applications on your phone. On Pixel and some other phones, tap “See all apps” next.
-
Find the malicious app.
The “Apps” screen will be displayed with a list of all the applications that are installed on your phone. Scroll through the list and look out for any suspicious app that could be behind all the drama – anything you don’t remember downloading or that doesn’t sound like a genuine program.
Most often, cyber criminals hide malware inside video or photo editing apps, weather apps, and camera apps.
-
Uninstall the malicious app
When you find a suspicious or malicious app, tap on it to uninstall it. This won’t start the app but will open up the app details screen. If the app is currently running press the “Force stop” button, then tap on “Uninstall”.
A confirmation dialog should be displayed to confirm you want to uninstall the app, tap on “OK” to remove the malicious app from your phone.
STEP 2: Stop spam notifications and redirects in your browser
In this second step, we will stop spam notifications in your browser. If unwanted pages or redirects still appear after that, we will reset the browser by clearing its app storage. That is a last resort, because it can delete data that isn’t synced.
Android browsers don’t have a single “reset settings” button like browsers on a computer, but they do let you control what each website is allowed to do. Start with the least disruptive fix: block the spam site’s notifications in the browser’s settings. In Chrome, you can also delete cookies and site data: tap More (three dots) > Delete browsing data.
Clear the browser’s app storage only if unwanted pages or redirects keep coming back. It works like a full reset, but it also deletes data that isn’t synced, so treat it as a last resort.
Remove malware from Chrome for Android
First, block the spam site’s notifications:
- Open Chrome, tap the More button (three dots) in the top-right corner, and tap Settings.
- Tap Site settings, then tap Notifications.
- Find the spam site in the list and turn off the switch next to it, or tap the site and block its notifications. To stop other sites from asking, you can also turn off the switch at the top.
If unwanted pages or redirects keep appearing, clear Chrome’s storage (last resort):
-

-
Tap “Clear all data”.
Tap “Clear all data” to delete all Chrome’s data including accounts, bookmarks, and your settings to reset the default settings.
-
Confirm by tapping “Ok”.
A confirmation dialog should now be displayed, detailing the components that will be restored to their default state should you continue with the reset process. To complete the restoration process, tap “Ok“.

-
Confirm by tapping “OK”.
A confirmation dialog will appear. Tap “OK” or “Delete” to finish. When you open Firefox again, sign back in and turn sync back on if you use it.
Remove malware from the Opera browser
First, block the spam site’s notifications:
- Open Opera, open the Opera menu, and tap Settings.
- Tap Site settings, then tap Notifications.
- Find the spam site and block it. Don’t just remove it from the list, because a removed site can ask again.

Remove Unwanted Apps and Malware from iPhone and iPad
STEP 1: Clean your browser
First, we’ll clean Safari using the built-in “Clear History and Website Data” feature. This removes your browsing history, cookies, and cached data — including the stored data that scam sites use to keep showing you pop-ups and redirects. Don’t worry: this won’t delete your photos, apps, or saved passwords, but it will sign you out of websites. To keep other sites signed in, you can remove only the scam site’s data instead: go to Settings > Apps > Safari > Advanced > Website Data, swipe left on the site, and tap Delete.
- Don’t tap anything inside the scam page or pop-up — the buttons are designed to trick you. Instead, tap the tabs icon in the lower-right corner of Safari, as shown below.
- Tap the X on the malicious tab (or swipe it up) to close it safely.
- Open the Settings app.
- Turn on Airplane Mode. This temporarily disconnects your iPhone from the internet, so the scam site can’t load anything while we clean up. We’ll turn it back off at the end.
- Scroll down and tap Apps, then tap Safari. On iOS 17 and earlier, Safari is listed directly in Settings.
- Tap Clear History and Website Data.
- If you’re asked to choose a timeframe, choose All history, then tap Clear History. On older iOS versions, tap “Clear History and Data” in the pop-up.
- While you’re still in Safari settings, turn on Block Pop-ups and Fraudulent Website Warning. These two switches stop most scam pages before they can even load.
- Tap Settings in the upper-left corner to return to the main Settings menu.
- Turn Airplane Mode back off to reconnect your iPhone to the internet.
STEP 2: Delete unwanted apps
Next, we’ll remove any suspicious apps from your iPhone. If a shady website redirected you to the App Store and you installed an app — or you spot an app you don’t remember downloading — delete it now:
-
On the home screen, tap and hold the unwanted app’s icon until the icons start to wiggle.
-
Tap the minus (–) badge in the corner of the app icon, then tap Delete App. (On older iOS versions, this badge appears as an “X”.)
-
Confirm by tapping “Delete“.
Now reopen Safari and check whether the pop-ups have stopped.
To stop these scam pages from coming back, we recommend installing an ad blocker like AdGuard. It blocks the malicious ads and redirects that cause these pop-ups in the first place.
Still having issues after completing these steps? Try one of the following:
- Run a scan with Malwarebytes for iOS
- Ask for help in our free Mobile Malware Removal Help & Support forum — our team will assist you personally.
When you’ve finished these steps, check whether the pop-ups or other problems have stopped.
Frequently Asked Questions About the “Threat Detected” Scam
1. What is the “Threat Detected: xxbc Detected” scam?
The “Threat Detected: xxbc Detected” scam is a fraudulent tech support scam affecting Windows and Mac users. It uses fake security pop-up alerts to convince victims that their device is infected. The pop-ups tell users to call a tech support number to remove the threats immediately. However, the pop-ups are completely fake and the numbers lead to criminal call centers intent on stealing your money and information.
2. How does the fake “Threat Detected” pop-up appear on my device?
The criminals use various deceptive methods to display the fake pop-ups, including:
- Malvertising – Clicking malware-laden fake ads and pop-ups while browsing shady sites.
- Compromised Sites – Visiting legitimate websites that have been hacked to show the pop-ups.
- Rogue Extensions – Browser extensions or plug-ins containing adware that injects the scam pop-ups.
- Bundled Software – Hidden scripts in some free downloaded programs that display the pop-ups.
- Mobile Push Notifications – Fake alerts sent as push notifications to phones and tablets.
3. Why do the pop-ups seem so real and legitimate?
The pop-up scammers put effort into making the fake alerts seem real to trick more victims. They spoof the look of authentic Windows, MacOS, and antivirus alerts using official logos and technical language. Many users mistake the pop-ups for legitimate warnings from Microsoft, Apple or their security software.
4. What happens if I call the tech support number in the pop-ups?
The numbers in the fake pop-ups lead to fraudulent call centers in India. Scammers there pose as Microsoft, Apple, or Google tech support and continue the deception. Through social engineering they will pressure and manipulate victims into paying for fake services, useless tools, and unnecessary “support packages.” They may also infect your device with malware or steal personal data.
5. How can the scammers access my computer remotely?
The scammers will convince victims to download remote access software like AnyDesk so they can “remove infections.” This allows the criminals to control your PC unsupervised and infect it with more malware, steal passwords, access bank details, install ransomware, etc. Never let unverified people remotely control your device.
6. What are some common scams the pop-up tech scammers try?
Some common scams they will try after you call include:
- Charging $200+ for fake long-term security or support packages.
- Selling you useless antivirus software for $499.
- Tricking you into paying $500+ to renew your license key which you don’t need.
- Getting you to buy gift cards and read them the redemption codes.
- Installing ransomware until you pay a bitcoin ransom to regain computer access.
7. What should I do if I already called the scam number and gave them money?
If you already fell victim, immediately end all contact with the scammers and block their numbers. Then reset all account passwords securely from another clean device and monitor your accounts closely for fraudulent charges. Report the scam to authorities, banks, and companies whose logos were misused. Learn from this experience to protect yourself in the future.
8. How can I remove pop-up malware and viruses if infected?
If you allowed remote access, save important data externally and scan your device with legitimate antivirus software like Malwarebytes. Also change all passwords again safely from another device. Be vigilant for new suspicious activity going forward. Avoid paying the scammers any more money.
9. What is the best way to protect myself from this scam?
Be cautious of any unsolicited pop-up, even if it looks official. Never call the number or allow remote access to your device. Use antivirus software, avoid shady sites and ads, inspect browser extensions, and keep software updated. Check site URLs carefully for subtle changes. Use common sense protection measures, and always think twice before believing pop-ups claiming your system is compromised.
10. Can these “Threat Detected” scam pop-ups infect Mac computers too?
Yes, Mac users are also targeted in this scam. The pop-ups often spoof Apple and MacOS alerts. Be just as suspicious of unsolicited warnings on Macs, iPhones, iPads and other Apple devices. Real Apple alerts would never demand you call a third-party number. Do not call the number or trust what the scammers tell you if you do.
The Bottom Line
The fake “Threat Detected: xxbc Detected” pop-up scam is a highly deceptive tech support scam. Using spoofed security alerts, it tricks Windows and Mac users into calling fraudulent support centers. These scammers then use social engineering and malware to steal personal information and money.
If you see this pop-up, remember:
- It is completely fake – do not call the number!
- Microsoft, Apple, and Google do not contact you this way.
- Close the page and run a system scan to be safe.
- Avoid shady websites and dodgy ads to prevent seeing the pop-ups.
Spread awareness about this scam to protect less tech-savvy people. With vigilance, we can shut down these criminal call centers and keep users safe online.
