If searches from a browser’s address bar are being redirected through Dfltsearch.com, then you most likely have an unwanted browser extension or a malicious program installed on your device.
What is Dfltsearch.com?
Dfltsearch.com is a search engine that is promoted through the use of malicious browser extensions and browser hijackers. When installed, these browser hijackers modify your web browser’s configuration to automatically send all searches through Dfltsearch.com.
When the Dfltsearch.com browser hijacker is installed on a computer, common symptoms include:
Your browser’s search queries are redirected through Dfltsearch.com
A malicious browser extension or program is installed on your computer
Why is my browser redirected to Dfltsearch.com?
Your browser is being redirected to Dfltsearch.com because a malicious browser extension or program is installed on your computer. Often, this type of program is offered through misleading advertisements or via adware, leaving the user puzzled about where this software came from. To block these types of malicious advertisements from the sites you visit, you can install an ad blocker like AdGuard [recommended].
If your computer starts redirecting you to Dfltsearch.com for no reason then you most likely have malware installed on the computer. To check your computer for adware, browser hijackers, or other malicious programs and remove them for free, please use the guide below.
Removal Instructions for Dfltsearch.com browser hijacker
This malware removal guide may appear overwhelming due to the number of steps and numerous programs that are being used. We have only written it this way to provide clear, detailed, and easy-to-understand instructions that anyone can use to remove malware for free. Please perform all the steps in the correct order. If you have any questions or doubts at any point, stop and ask for our assistance.
Browser hijackers and adware can infect Windows, Mac, or Android devices, so we’ve covered below all these operating systems. Depending on which operating system is installed on the device you’re seeing the Dfltsearch.com redirect, please click on the operating system icon below and follow the displayed steps to remove it.
STEP 1: Use Rkill to terminate malicious processes
In this first step, we will download and run Rkill to terminate malicious processes that may be running on your computer.
RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections. When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies that stop us from using certain tools.
Download Rkill.
You can download RKill to your computer from the below link. When at the download page, click on the Download Now button labeled iExplore.exe. We are downloading a renamed version of Rkill (iExplore.exe) because some malware will not allow processes to run unless they have a certain filename.
RKILL DOWNLOAD LINK (The above link will open a new page from where you can download Rkill)
Run RKill.
After downloading, double-click the iExplore.exe icon to kill malicious processes. In most cases, downloaded files are saved to the Downloads folder. The program may take some time to search for and end various malware programs.
When it is finished, the black window will close automatically and a log file will open. Do not restart your computer. Proceed to the next step in this guide.
STEP 2: Uninstall malicious programs from your computer
In this second step, we will manually check if any unknown or malicious programs are installed on the computer. Sometimes adware and browser hijackers can have a usable Uninstall entry that can be used to remove them.

With the malicious programs removed, you’re ready for the next step in this guide.
STEP 3: Remove malicious browser policies from Windows
In this third step, we will download the Chrome Policy Remover file (credits to Stefan Van Damme) and remove the malicious browser policies. .
Download the Chrome Policy Remover.
Download the “Chrome Policy Remover for Windows” file from the below link. This file is a batch script designed to automatically remove Chrome policies.
Note: Windows might display a security warning because the file is a batch script (.bat). This is a standard security measure. Since the Chrome Policy Remover is a trusted tool, clicking “Keep” allows you to proceed with the download.
Right-click “delete_chrome_policies.bat” file and select Run as administrator
We will now run the “delete_chrome_policies.bat” fiel as administrator.Running the delete_chrome_policies file as administrator grants it the necessary permissions to modify system settings related to Chrome policies. This ensures the tool can effectively remove the policies.
Click Yes/Run at the confirmation prompt and allow the process to complete.
Windows will ask for confirmation before allowing the script to make changes. Clicking “Yes” or “Run” (depending on your Windows version confirms your intent to run the tool and remove the Chrome policies. The script will then run and automatically remove the policies, after which you can close the command prompt window.
Now that the malicious policies were removed, in the next step, we will reset your browser settings to their defaults.
STEP 4: Remove malicious files and folders from Windows
In this fourth step, we will manually search and remove malicious scheduled tasks and folders on your computer.
1. Delete malicious scheduled tasks.
This infection may create a malicious scheduled task in the Task Scheduler to ensure that it is automatically reinstalled every 5 minutes after it has been deleted. This task may run at regular intervals to ensure that the infection persists on your system.
Search for “Task Scheduler” in the windows search as shown below..
You can also open the Task Scheduler app by pressing the Windows + R buttons and then type “taskschd.msc” and press Enter.
In the Task Scheduler window, navigate to the Task Scheduler Library on the left side of the screen.
Locate the malicious scheduled task in the list of tasks. It may have a randomly generated name (eg. Chrome_Policy, Chrome_Bookmarks, Chrome_Folder) or may be identified as a suspicious or unknown task. Right-click on the malicious task and select “Delete” from the menu.
2. Delete malicious files located in AppData\Roaming folder
We will now delete the malicious file that is located in the AppData\Roaming folder.
Search for “Run” in the windows search as shown below, or press the Windows + R button to open the Run app.
In the run app text box, enter “%AppData%” and click OK. Windows will directly open up the Roaming folder which is inside the AppData folder.
In the AppData\Roaming folder, search and delete any unknown folders with names like Default, Chrome32, Energy, Bloom, and Travel (note that the actual name on your computer may be different, but you should look for programs with similar naming conventions).
3. Delete malicious files located in AppData\Local folder
Next, we will delete the malicious folders that are located in the AppData\Local folder and the malicious Chrome browser extensions.
Search for “Run” in the windows search as shown below, or press the Windows + R button to open the Run app.
In the run app text box, enter “%localappdata%” and click OK. Windows will directly open up the AppData\Local folder which is inside the AppData folder.
In the AppData\Local directory, search and delete the Default,WindowsApp and ServiceApp folders.
Next, find the Google folder and go to Google > Chrome > User Data > Default (or Profile) > Extensions. Find the malicious extension folder within the Extensions folder and delete it. It may have a randomly generated name or may be identified as a suspicious or unknown extension.
4. Remove Chrome Shortcut Modification
This malware can hijack your browser shortcuts to target the malicious files. Here is a short guide on how to remove the Chrome shortcut modification:
Right-click on the Google Chrome shortcut on your desktop or Start Menu and select “Properties“.
Under the Shortcut tab, look for the “Target” field. This is where any added commands to the shortcut will be. Carefully examine the target path and remove any suspicious looking text that may have been appended, especially anything referencing the AppData folder. For example, remove text like “–load-extension=C:\Users%USERNAME%\AppData\Local\Default”. The target should point only to the chrome.exe file location, nothing more.
Click OK to save the changes and close Properties.
Launch Chrome again normally through the shortcut. The extension should no longer load on start up.
You can also right click the shortcut and select “Open File Location” to open the chrome.exe folder. Drag chrome.exe directly to your taskbar to create a clean shortcut.
Now that we have manually removed the malicious tasks and folders from your computer and cleaned your browser shortcuts, we can continue with the next step.
STEP 5: Reset your browser settings to their defaults
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 this method will remove all extensions, toolbars, and other customizations but will leave your bookmarks and favorites 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.
ChromeFirefoxMicrosoft EdgeInternet Explorer
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
In the top-right corner of Chrome, click the three-dot (⋮) icon to open the menu.
Go to Settings
From the menu, select Settings.
Select “Reset settings”
In the left sidebar, scroll down and click Reset settings.
Choose “Restore settings to their original defaults”
Click Restore settings to their original defaults.
Confirm the reset
In the dialog that appears, click Reset settings. This restores your homepage, search engine, new tab page, and pinned tabs to default, disables all extensions, and clears temporary site data — undoing the changes the malware made.
Don’t worry: your bookmarks, history, and saved passwords are safe and will not be deleted.
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”
Click the three horizontal lines in the top-right corner of Firefox to open the main menu, then select “Help“.

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” — your Firefox is now clean.
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.
Click the three dots in the top-right corner and then click on “Settings”.
In the top right corner, click on Microsoft Edge’s main menu button, represented by three horizontal dots. When the drop-down menu appears, click on “Settings“.
Click on “Reset Settings”.
On the left side of the window, click on “Reset Settings“.
Click on “Restore settings to their default values”.
In the main window, click on “Restore settings to their default values“.
Click “Reset”.
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” button. Microsoft Edge will now erase all your personal data, browsing history, and disable all installed extensions. Your bookmarks, though, will remain intact and still be accessible.
Reset Internet Explorer to default settings
We will now reset your Internet Explorer browser settings to their default. You can reset Internet Explorer settings to return them to the state they were in when Internet Explorer was first installed on your computer.
Go to “Internet Options”.
Open Internet Explorer, click on the gear icon in the upper-right part of your browser, then select “Internet Options“.
Select the “Advanced” tab, then click “Reset”
In the “Internet Options” dialog box, select the “Advanced” tab, then click on the “Reset” button.
Click on “Reset”.
In the “Reset Internet Explorer settings” section, select the “Delete personal settings” checkbox, then click on the “Reset” button.
Click on “Close”.
When Internet Explorer has completed its task, click on the “Close” button in the confirmation dialogue box. Close your browser and then you can open Internet Explorer again.
STEP 6: Use Malwarebytes to remove trojans and browser hijackers
In this step, we will install and run a scan with Malwarebytes Free to 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 and clean your PC in just a few minutes.
Download Malwarebytes
Click the button below to download the latest version of Malwarebytes for Windows from the official source. The free version is all you need — it will scan your computer and remove adware, browser hijackers, and other malicious software at no cost.

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, your PC is clean and you can continue with the next steps in this guide.
STEP 7: Use HitmanPro to scan your computer for rootkits and other malware
In this next step, we will scan the computer with HitmanPro to ensure that no other malicious programs are 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 gets sent to the cloud, where it’s analyzed by two of the best antivirus engines available: Bitdefender and Kaspersky.
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 clean your PC at no cost. (A full license is $24.95 per year for 1 PC.)
Download HitmanPro
Click the button below to download HitmanPro. Remember — the scan is free, so you have nothing to lose by checking your PC.
When the download finishes, open your Downloads folder and double-click the file: “hitmanpro.exe” on 32-bit Windows, or “hitmanpro_x64.exe” on 64-bit Windows.
If a User Account Control pop-up asks whether HitmanPro can make changes to your device, click “Yes” to continue.
Follow the On-Screen Prompts
On the HitmanPro start screen, click “Next” to begin the system scan. No lengthy setup required — it goes straight to work.
Wait for the Scan to Finish
HitmanPro will now check your computer for malicious programs. This usually takes just a few minutes thanks to its cloud-based scanning.

When the scan is done, HitmanPro will show you everything it found. Click “Next” to remove the detected threats.
Click “Activate Free License”
To remove the malicious files, click the “Activate free license” button. This starts your free 30-day trial — no payment details needed — and unlocks the full cleanup.
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, just click Close — your PC is clean.
STEP 8: Use AdwCleaner to remove adware and malicious browser policies
In this final step, we will download and install 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.
Download AdwCleaner
Click the button below to download AdwCleaner — it’s free, portable, and requires no installation.
Open your Downloads folder and double-click the file named “adwcleaner_x.x.x.exe“. There’s no installation — the program starts right away.
If Windows asks whether you want to allow AdwCleaner to run, click “Yes“. When the license agreement appears, click I agree to continue.
Enable “Reset Chrome policies”
This setting removes malicious browser policies — a trick malware uses to lock your browser settings so you can’t change them back. Click “Settings” on the left side of the window, then turn on “Reset Chrome policies“.
Start the Scan
Click “Dashboard” on the left side of the window, then click the “Scan” 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 will list everything it found. Click the “Quarantine” button to remove all the malicious items at once.
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 delete all detected malware from your computer. If it asks you to restart your PC, allow it — your computer will be clean when you log back in.
Your computer should now be free of the Dfltsearch.com redirect virus and other malware.
If your current antivirus allowed this malicious program on your computer, you may want to consider purchasing Malwarebytes Premium to protect against these types of threats in the future. If you are still having problems with your computer after completing these instructions, then please follow one of the steps:
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 Preferences”
From the Apple menu, select System Preferences.
Search for “Profiles”
When the System Preferences window opens, search for the Profiles icon.
If there isn’t a Profiles icon, you don’t have any profiles installed, which is normal and you can continue with the next steps.
Remove the malicious profiles
If there’s a Profile icon, click on it and select any suspicious profile that you want to remove, and then press the – (minus) button. Click Remove to remove the profile.
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
On the Apple menu bar, in the top-right corner, if you see any unknown or suspicious icon, click on it and then select Quit.
Open “Finder”
Click the Finder application on your dock.
Click on “Applications”
In the Finder left pane, click on “Applications“.
Find and remove the malicious app.
The “Applications” screen will be displayed with a list of all the apps installed on your device. Scroll through the list until you find the malicious app, right-click it, and then click “Move to Trash”.
Look out for any suspicious program that could be behind all the drama – anything you don’t remember downloading or that doesn’t sound like a genuine program. Here are some known malicious programs: SearchMine, TakeFresh, TopResults, FeedBack, ApplicationEvents, GeneralOpen, PowerLog, MessengerNow, ImagePrime, GeneralNetSearch, Reading Cursors, GlobalTechSearch, PDFOnline-express, See Scenic Elf, MatchKnowledge, Easy Speedtest, or WebDiscover.
Click “Empty Trash”
On the dock, right-click on the trash icon and select “Empty Trash”. Doing so deletes the Trash’s contents, including the program that you just sent to the Trash.
Find and remove the malicious files
Click the desktop to make sure you’re in the Finder, choose “Go” then click on “Go to Folder“.
Type or copy/paste each of the below paths into the window that opens, then click Go.
/Library/LaunchAgents
~/Library/LaunchAgents
/Library/Application Support
/Library/LaunchDaemons
Look out for any suspicious files that could be behind all the drama – anything you don’t remember downloading or that doesn’t sound like a genuine program. These are some known malicious files: “com.adobe.fpsaud.plist” “installmac.AppRemoval.plist”, “myppes.download.plist”, “mykotlerino.ltvbit.plist”, or “com.myppes.net-preferences.plist”. When you find a malicious file move it to the Trash.
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.

Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.
Stop and verify before you click, log in, download, or pay.
Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).
If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.
Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.
If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.
Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.
If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.
Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.
If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.
Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.
If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.
Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.
If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.
Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.
If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).
Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.
If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.
Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.
If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.
Move quickly. Speed matters for disputes, account recovery, and limiting damage.
Stop payments and contact: do not send more money or respond to the scammer.
Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
Scan your device: remove suspicious apps or extensions, then run a full malware scan.
Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.
These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
