How to Fix Windows Security Detecting Google Chrome as Virus

If you are a Windows user, you may have encountered a problem where Windows Security (the built-in antivirus and firewall software) flags Google Chrome as a virus and blocks it from running. This can be very frustrating, especially if you rely on Chrome for your daily browsing needs. In this blog post, we will explain why this happens and how you can fix it.

Virus Chrome

Why does Windows Security flag Chrome as a virus?

There are several possible reasons why Windows Security may flag Chrome as a virus. One of them is that Chrome may have been infected by malware or adware that modifies its settings or behavior. Another reason is that Windows Security may have a false positive, meaning that it mistakenly identifies Chrome as a threat when it is not. A third reason is that there may be a conflict between Windows Security and Chrome’s own security features, such as sandboxing or safe browsing.

How can you fix Windows Security detecting Google Chrome as virus?

Reset Chrome and scan your device for malware

The first thing you should do is to make sure that your Chrome is up to date and free of malware or adware. You can do this by following these steps:

STEP 1: Reset browsers back to default settings

First, we’ll reset your browser to its default settings — this removes the spam notification permissions, malicious extensions, and unwanted search engines in one go.
Don’t worry: the reset removes extensions, toolbars, and customizations, but your bookmarks and favorites stay intact.
For each browser installed on your computer, click its tab below and follow the steps to reset it.

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.

  1. Open the Chrome menu


    Open Google Chrome and click the three-dot (⋮) icon in the top-right corner.


    Click the three-dot menu icon in Chrome
  2. Open Chrome Settings


    Select Settings from the Chrome menu.


    Select Settings from the Chrome menu
  3. Select “Reset settings”


    Look at the menu on the left side of the Settings page. Scroll down and click Reset settings.


    Click Reset settings in the Chrome sidebar

  4. Restore Chrome’s original settings


    Click Restore settings to their original defaults.


    Choose Restore settings to their original defaults


  5. 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

    • Disable installed extensions

    • Clear temporary cookies and website data


    Don’t worry: Chrome will not delete your bookmarks, browsing history, or saved passwords.


    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.


    Confirm the Chrome reset
  6. 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:



    1. Open a new Chrome tab.

    2. Copy the following address, paste it into Chrome’s address bar, and press Enter:
      chrome://settings/syncSetup/advanced


    3. Under Manage what you sync, select Customize sync.

    4. Turn off Settings and Extensions.

    5. 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.

    1x 1

    Now save anything you are working on and close every Chrome window.


    Run the cleanup command:



    1. Press the Windows key on your keyboard.

    2. Type PowerShell.

    3. Open Windows PowerShell. Administrator access is not required.

    4. Copy the entire command shown below.

    5. Right-click inside the PowerShell window to paste the command, then press Enter.

    6. 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.
    1 32

    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 and form suggestions.


    The original search database is not deleted. PowerShell renames it and adds search-hijacker-backup to 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.

  1. 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“.
    Click on the Firefox Menu button then select Help button

  2. Click “More troubleshooting information”

    In the Help menu, click “More troubleshooting information“.
    Click More Troubleshooting Information

  3. Click “Refresh Firefox”

    On the “Troubleshooting Information” page, click the “Refresh Firefox” button in the top-right area of the page.
    Click on Refresh Firefox

  4. 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 again on Refresh Firefox button

  5. 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.

Updated for Microsoft Edge on Windows 10 and Windows 11 — July 2026.

  1. Open the Edge menu and click “Settings”

    Open Microsoft Edge. In the top-right corner, click the three-dot (…) icon, then click Settings.

    Open the Microsoft Edge menu and click Settings
  2. 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/sync

    On 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.

  3. 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
    Open Reset settings in Microsoft Edge
  4. Click “Restore settings to their default values”

    Click Restore settings to their default values.

    Select Restore settings to their default values in Microsoft Edge
  5. 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.

    Confirm the Microsoft Edge reset
  6. Check your extensions before turning them back on

    Copy the following address, paste it into the Edge address bar, and press Enter:

    edge://extensions

    Remove 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.

  7. Select a trusted search engine

    Copy the following address, paste it into the Edge address bar, and press Enter:

    edge://settings/searchEngines

    Select Bing, Google, DuckDuckGo, or another search provider you trust and make it the default.

    Remove any unknown search engines, especially providers with strange names or addresses that you did not add yourself.

    Restart Edge and perform a search from the address bar. If searches are no longer redirected, you can stop here.

  8. 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.

    1. Open the Windows Start menu.
    2. Type PowerShell.
    3. Open Windows PowerShell. Administrator access is not required.
    4. Copy the entire command below.
    5. 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, and manually added search engines. It does not delete favorites, passwords, or browsing history.

  9. Reopen Edge and test the browser

    Open Microsoft Edge again, visit edge://settings/searchEngines, and select your preferred search engine.

    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.

  10. 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.

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.

  1. Go to “Internet Options”.

    Open Internet Explorer, click on the gear icon in the upper-right part of your browser, then select “Internet Options“.

  2. Select the “Advanced” tab, then click “Reset”

    In the “Internet Options” dialog box, select the “Advanced” tab, then click on the “Reset” button.

  3. Click on “Reset”.

    In the “Reset Internet Explorer settings” section, select the “Delete personal settings” checkbox, then click on the “Reset” button.

  4. 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.

With the site’s permission to send push notifications removed, the pop-ups should stop. Next, we’ll scan your computer to make sure no adware or malicious program is behind them.


STEP 2: Use Malwarebytes Anti-Malware to remove malware and unwanted programs

Now we’ll install Malwarebytes and run a scan to detect and remove any infections, adware, or potentially unwanted programs 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.

    MBAM14

STEP 3: Use HitmanPro to scan for rootkits and other malware

Finally, we’ll run a second-opinion scan with HitmanPro to confirm nothing was missed. If this scan comes back clean, your computer is malware-free.

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.)

  1. Download HitmanPro

    Click the button below to download HitmanPro. Remember — the scan is free, so you have nothing to lose by checking your PC.

  6. 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.
    Click on the Activate free license button

    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.

Add Chrome as an exception in Windows Security

If this does not solve the problem, you can try to add Chrome as an exception in Windows Security. This will tell Windows Security to ignore Chrome and allow it to run normally. You can do this by following these steps:

  1. Open Windows Security and click on Virus & threat protection.
  2. Under Virus & threat protection settings, click on Manage settings.
  3. Under Exclusions, click on Add or remove exclusions.
  4. Click on Add an exclusion and select Folder.
  5. Browse to the folder where Chrome is installed, usually C:\Program Files (x86)\Google\Chrome\Application.
  6. Click on Select Folder and confirm the exclusion.

Disable Windows Security temporarily and see if Chrome works

If this does not solve the problem either, you can try to disable Windows Security temporarily and see if Chrome works. However, this is not recommended as it will leave your computer vulnerable to other threats. You can do this by following these steps:

  1. Open Windows Security and click on Virus & threat protection.
  2. Under Virus & threat protection settings, click on Manage settings.
  3. Turn off the toggle for Real-time protection.
  4. Try to run Chrome and see if it works.
  5. Turn on the toggle for Real-time protection again.

We hope that this blog post has helped you fix the problem of Windows Security flagging Chrome as a virus. If you have any questions or feedback, please leave a comment below.
