I have a browser hijacker

[Lindashay]

Have a browser hijacker (tfrsrch.com) on my HP laptop that I cannot get rid of. I have Norton and Malwarebytes and have spent HOURS on line with both and they obviously can't get rid of it either.

@Lindashay,

Welcome to our HP Community forum!

When standard antivirus software like Norton and Malwarebytes fail, it is usually because the hijacker (tfrsrch.com) has modified your browser's shortcut properties, installed a hidden malicious extension, or altered your system's DNS settings.

Since it appears that automated tools aren't working, follow these manual steps to root it out:

1. Fix Browser Shortcuts:

The hijacker often appends its URL to the end of your browser's "Target" path, causing it to load every time you open the app.

• Right-click your browser icon (Chrome, Edge, etc.) on your desktop or taskbar.
• Select Properties and go to the Shortcut tab.
• Look at the Target field. It should end in ...chrome.exe" or ...msedge.exe".
• If there is a URL like tfrsrch.com after the quotes, delete that text and click OK.

2. Remove Malicious Extensions & Reset Startup:

Even if you didn't install them, "managed" extensions can force redirects.

• Chrome/Edge Extensions: Go to Settings > Extensions and remove anything you don’t recognize.
• Reset Startup Page: In browser Settings, go to On startup. If "Open a specific page" is selected, remove tfrsrch.com and set it to Open the New Tab page.
• Reset Search Engine: Go to Search engine settings and ensure your default is set to Google or Bing; delete any suspicious entries in the Manage search engines list.

3. Clear DNS Cache and Temporary Files:

Malware can "poison" your DNS to redirect your traffic even if the browser looks clean.

• Flush DNS: Search for cmd, right-click it to Run as Administrator, type ipconfig /flushdns, and press Enter.
• Clear Temp Files: Press Windows Key + R, type %temp%, and delete everything in the folder that opens.

4. Use Advanced Specialized Tools:

If Norton and Malwarebytes failed, try these highly effective, free specialized scanners:

• AdwCleaner: A tool by Malwarebytes specifically designed to find "Potentially Unwanted Programs" (PUPs) and hijackers that the main suite might miss.
• HitmanPro: A secondary scanner that is excellent at finding deeply embedded remnants.
• Microsoft Safety Scanner: A free, on-demand tool from Microsoft that uses the same engine as Windows Defender but is often more aggressive.
• Reference link: How do I get rid of a web hijacker when malwarebytes cant detect it | Tom's Guide Forum.

5. The "Nuclear" Option: Browser Reset:

If the hijacker persists, you can restore your browser to its original factory state.

• Go to Settings > Reset settings.
• Click Restore settings to their original defaults. This will disable all extensions and clear temporary data while keeping your passwords and bookmarks.

Question: do you notice if tfrsrch.com appears only in one specific browser, or does it happen across all browsers on your laptop?
