In extreme cases, the hijacker reinstalls itself on the browser and users may need to delete the contents of their computer, install a new operating system and the latest browser version, and restore their personal files from a backup.

Method 1: Remove suspicious and unnecessary extensions and toolbars. They can be reinstalled, so you may want to remove everything. Then close your browser and restart your computer.


Once your computer has restarted, make sure what you deleted is still gone. If so, change your browser settings (default search engine, home page, etc.) to ensure that what you have deleted is always gone. - and everything will return to normal. If you are still being redirected or if an extension is not uninstalled, you should continue.

Method 2: Clear your DNS cache. On Windows, you need to open the command prompt and type the following:


ipconfig / flushdns

  1. Hit "enter" and clear the DNS cache. You will then see "Windows IP settings successfully cleared DNS resolver cache."
  2. Clearing it will restore DNS redirects to your network settings.

Method 3- Browse the Add or Remove Programs section and remove the apps connected to the browser hacker. If you don't see something, be sure to scan it before deleting, preferably on a non-infected device.


Restart the computer and verify that the problem is resolved.

Method 4: Check your proxy settings again. Some hackers can even modify the Internet server you use to connect to the Web. Basically removing the malware or the malware itself doesn't change anything, so it's an important step in restoring your computer.


  1. To access your proxy settings, go to Control Panel first, then Network and Internet, then Internet Options.
  2. In the Internet Options menu, go to the Connections tab. Press the LAN Settings button.

Browser hijacking is common, and in several cases, users are unaware that their browser is infected with some malware.

Thus, it is essential to always carefully read the steps of the installation procedure and check the unexpected boxes that can be checked by default. At the same time, never open URLs or attachments in emails that you don't trust.

In addition, caution should be exercised with browser extensions, as many browser extensions are generally out of date and thus misused by hackers for fraudulent activities. Hackers themselves design browser extensions to later infect them with malicious scripts.

Every time you surf the web and are prohibited from visiting a web portal, and Google's safe browsing listing pops up with a warning message, it is best not to ignore it or visit the site anyway.

The good news is that browser hacking doesn't have to happen to you now that you know what it is. Remember these methods to avoid it, and you won't fall for fraudulent scammers!
