Hi everybody, I still get popups..........?

like utarget, adultfriendfindre, and other dating crap related windows, also from http://a.as-eu.falkag.net, some popups are just blank. I do have norton internet security and firewall and popup blockers, all on. Yet these things are still coming. I installed spybot search and destroy, spyware blaster, ad aware se, after running them I ended up not being able to log into internet. Please, can you tell me whatta heck is going on?
