I keep having pop-under adds popping up in explorer all the time. There is one that pops up in firefox. I've run AVG virus and Add aware in safe mode and am still having problems. There were no problems in safe mode. I'm pretty sure it came from something I downloaded and clicked on. This has been deleted.
Is there anything I can do that I haven't tried yet? Any idea what's happening? Or am I stuck re-installing windows?
