Recently, I've had trouble with constant audio ads running in the background, even when I don't have a browser open. I can't be certain but I think this and some other ads that intermediately come up on sites like google and youtube have something to do with a proxy server that I can't get rid of, and/or some .exe programs (internetport3.exe and getcap.exe) that I can't seem to shake either. I've tried Malwarebytes as well as HitmanPro and RougeKiller, all before coming to this site looking for help. I've also read the "I'm Infected-What do I do now?" thread and have followed the steps there. I appreciate the help.
