@gibmenamepls As @leocg suggests, disable your browser extensions and see if it stops the problem. If it does, you'll need to isolate and remove the extension at fault by the process of elimination. Enable all the extensions, disable one of them and test to see if the problem goes away. Repeat the same process for each extension one at a time, and remove/uninstall each extension that causes the problem to reoccur. (I've seen users who have more than one infected extension installed.)
If browser extensions are not causing the problem, a robustsearch adware infection is also known to result from installing an infected software program elsewhere on the computer, but this form of adware can remain undetected by many antivirus programs. Was there something you recently installed on your computer (just prior to when the problem started)?
