Remove unwanted ads, pop-ups & malware
If you're seeing some of these problems with Chrome, you might have unwanted software or malware installed on your computer:
- 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
In the future, avoid unwanted software by only downloading files or visiting sites that you know are secure.
