Windows Defender and Microsoft Safety Scanner-Still have adware

I have windows defender and have run a full system scan.  No virus or malware found. But when I use mozilla firefox, chrome, or explorer I still get pop ups of various ads.  I don't know what to do.  I did have Norton and still do, but uninstalled it and turned on windows defender to see if the Norton was just missing something, but apparently it is not.  What do I need to do?
