First port of call mate would be to download:
Spybot S&D
Adaware
Update those programs and run them, theres a good chance some of you pop-up phlight might be a result of adware and other registry entries.
Then install the microsoft pop-up blocker, as they are pretty standard in what they do (block pop-ups). Be careful of some as the pop-up blockers themselves install adware and other junk.
