Stop unwanted pop-ups or homepage changes

If you're seeing pop-up ads that won't go away, or the homepage you set is gone, you may 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 from getting installed in the future.

Look for malware and unwanted programs

Here are some clues that a suspicious program is affecting Google Chrome:

  • Chrome 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 Chrome
  • The Chrome desktop shortcut opens an unfamiliar website

These changes may be caused by malicious software known as malware. You can get malware from downloading files or visiting insecure sites. If you’ve found a site that you think has malware, report the malicious site.
