Too many pop-ups could indicate a malware infection, so as well as installing, updating and running Ad Aware and Spybot, it's worth posting a HJT log, just to be sure, and then installing Panicware's Pop-Up Stopper, as linked to via page 6 of "Barney's Place". I'd also suggest installing Clean Temp (page 4) to be sure there isn't something nasty lurking in the C:\Windows\Temp folder.

Everything I link to is free, so have a wander round the site and help yourself to anything you need.
