How to Remove a Browser Redirect Virus on Windows

What Causes This?

A browser redirect virus is usually caused by a browser hijacker, malicious extension, bundled freeware, or adware that changes your browser settings without clear permission. It may alter your default search engine, homepage, new tab page, shortcut target, DNS settings, or startup entries so redirects keep coming back. In some cases, the problem is tied to a suspicious app installed in Windows rather than the browser itself.

Common Symptoms

• Searches open in the wrong search engine or on random websites
• Your homepage or new tab page changes on its own
• Extra ads, pop-ups, or fake update warnings appear
• Browser shortcuts open strange URLs when launched
• Redirects return even after you reset browser settings

How to Fix It Manually

1. Uninstall suspicious apps from Windows

   • Press Windows + I to open Settings.
   • Go to Apps > Installed apps.
   • Sort by Install date and look for anything unfamiliar, recently installed, or clearly unwanted.
   • Click the three dots next to a suspicious app and choose Uninstall.

2. Disable and remove suspicious browser extensions

   • In Chrome, open chrome://extensions
   • In Edge, open edge://extensions
   • In Firefox, open about:addons
   • Remove anything you don’t recognize, especially coupon tools, “search helpers,” VPN/proxy add-ons you didn’t install, or extensions marked “Installed by enterprise policy” without a valid reason.

3. Reset your browser settings

   • In Chrome: Settings > Reset settings > Restore settings to their original defaults
   • In Edge: Settings > Reset settings > Restore settings to their default values
   • In Firefox: open about:support and click Refresh Firefox
   • This clears hijacked startup pages, search settings, and temporary browser changes.

4. Check browser shortcuts for added redirect URLs

   • Right-click your browser shortcut on the Desktop or Taskbar, then select Properties.
   • In the Shortcut tab, check the Target field.
   • It should end with only the browser executable, such as:
     • "C:\Program Files\Google\Chrome\Application\chrome.exe"
     • "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe"
   • If you see a website address added after .exe, delete that extra text and click Apply.

5. Remove suspicious startup items

   • Open Task Manager with Ctrl + Shift + Esc.
   • Select the Startup apps tab.
   • Disable anything unknown, especially items with no publisher or names tied to adware/search tools.
   • Restart your PC after disabling them.

6. Clear DNS and check proxy settings

   • Right-click Start and choose Windows Terminal (Admin) or Command Prompt (Admin).
   • Run:
     1. ipconfig /flushdns
     2. netsh winsock reset
   • Then go to Settings > Network & internet > Proxy and make sure a proxy server is not enabled unless you intentionally use one.

7. Run Windows Security

   • Open Start, type Windows Security, and open it.
   • Go to Virus & threat protection > Scan options.
   • Run a Full scan.
   • Remove or quarantine anything it finds, then restart your PC.
