If you’re seeing the pop-up ads on every website you visit, or if your browser’s homepage has been changed unexpectedly, it’s possible your browser has been infected by adware. Adware is a type of malware that injects ads into web pages in such a way that they can't be blocked. The only way to get rid of these ads is to remove the malware. You’ll find the basic steps for finding and removing adware and other types of malware below.
Check for malicious extensions
Type about:extensions in the address bar to open the list of extensions. Remove any extensions that you don’t remember installing or that you recently installed (especially if the ads started appearing immediately after you installed it).
