Pop-ups, redirects, and other malware
If you're seeing pop-up ads that won't go away, or you suddenly have a homepage that you know you didn't set, you might have an unwanted program installed on your computer. Here are some steps you can take to get rid of this program and block similar ones in the future.
Clues to tell if you have an unwanted program
- Your browser doesn't block pop-up ads from showing
- Your homepage, startup page, or search engine has changed to a site you don't recognize
- Unfamiliar extensions or toolbars are added to your browser
- You're seeing a search engine that looks like Google, but with the wrong logo or web address
These changes may be caused by harmful software known as malware.

Protect your browser from malware
Here are two common ways that people get malware:
- Downloads: Sometimes you download a program to let you do certain things online, but the program also contains bad software. Even though you can see and use the program you wanted, the other program might be running in the background. These additional programs can do things like add toolbars or ads to your browser.
- Extensions: Safe extensions that you have on your computer are sometimes purchased by hackers. When they update the extension, they can install malware onto your computer.
To protect your computer from malware in the future, only click links and downloads from sites that you trust.
