How to remove unwanted ads, pop-ups and malware


You might have unwanted software or malware installed on your computer if you experience:

  • Pop-up ads and new tabs that won't go away
  • Your Chrome homepage or search engine keeps changing without your permission
  • Unwanted Chrome extensions or toolbars keep coming back
  • Your browsing is hijacked, and redirects to unfamiliar pages or ads
  • Alerts about a virus or an infected device.


  • Chrome OS devices


To prevent intrusive or misleading ads, change your site settings.

  1. On your computer, open Chrome.
  2. At the top right, click More > Settings > Privacy and security.
  3. Click Site settings > Additional content settings > Intrusive ads.
  4. Select the option you want as your default setting.
You can disable extensions and test them one by one to disable or discontinue the one with the issue.


Some extensions may push malware or non-allowed configurations to the Chrome OS devices.
