Have you ever opened your browser only to find that your homepage has changed, or your searches are being redirected to a strange website like Yahoo or Bing instead of Google? You are likely dealing with a browser hijacker. These are malicious software programs or rogue extensions that modify your browser settings without permission to generate ad revenue or track your activity.

In this guide, we will walk you through the step-by-step process of identifying and removing browser hijackers from Google Chrome, Microsoft Edge, and Mozilla Firefox.

Step 1: Identify and Remove Suspicious Browser Extensions

Most hijackers live within browser extensions. These are often disguised as helpful tools like "PDF Converters" or "Weather Trackers."

• Google Chrome: Type chrome://extensions/ in the address bar. Look for any extension you don't remember installing. Click Remove on anything suspicious.
• Microsoft Edge: Type edge://extensions/ and toggle off or Remove unrecognized add-ons.
• Firefox: Type about:addons and select Extensions to manage and delete rogue entries.

Step 2: Reset Your Browser to Default Settings

Even after removing the extension, the hijacker may have altered your search engine and homepage settings. The fastest way to fix this is a full reset.

• For Chrome: Go to Settings > Reset settings > Restore settings to their original defaults. This will disable all extensions and clear temporary data without deleting your bookmarks or passwords.
• For Edge: Go to Settings > Reset settings > Restore settings to their default values and click Reset.

Step 3: Clean Your Browser Shortcuts

Some advanced hijackers modify the actual shortcut icon on your desktop to force the browser to open a specific malicious URL every time you launch it.

1. Right-click your browser icon (e.g., Chrome) on your desktop or taskbar.
2. Select Properties.
3. Look at the Target field. It should end in chrome.exe". If there is a URL listed after the quotes, delete that URL and click Apply.

Step 4: Run a Specialized Malware Scan

Standard antivirus software sometimes misses browser hijackers because they are classified as "Potentially Unwanted Programs" (PUPs). To ensure your system is clean, use a specialized tool.

• Download and run Malwarebytes ADWCleaner. This tool is specifically designed to target and destroy browser hijackers, toolbars, and PUPs.
• Perform a full system scan with Malwarebytes Free to ensure there are no hidden trojans or rootkits assisting the hijacker.

Step 5: Check Your Hosts File (Advanced)

If the redirects persist across all browsers even after a reset, the malware may have edited your Windows Hosts file.

1. Open the Start Menu, search for Notepad, right-click it, and select Run as Administrator.
2. Go to File > Open and navigate to: C:\Windows\System32\drivers\etc\
3. Change the file type to All Files and open hosts.
4. Look for any lines at the bottom that list IP addresses followed by website names (like google.com). Delete any suspicious entries and save the file.

How to Prevent Future Browser Hijacks

To keep your browser secure in the future, follow these Cybersecurity best practices:

• Avoid "Bundled" Software: When installing free software, always choose the "Custom" or "Advanced" installation to uncheck optional toolbars or search engines.
• Check Permissions: Before adding a browser extension, read the permissions it requires. If a calculator app wants to "read and change all your data on the websites you visit," do not install it.
• Keep Software Updated: Ensure your browser and operating system are always running the latest security patches to close vulnerabilities.

💡 Pro Tip: Keep your software updated to avoid these issues in the future.
