How do i get rid of annoying pop ups?spyware removal

Try Zone Alarm Pro.

Im using that, and i have never received pop ups.
popup stopper is useless, as they are installed, stoppers only stop incoming. sounds like spyware. spybot updated or any good spyware scanner should help. adaware se, might.
When the pop ups are trying to sell bogus antispyware and such, that's generally a smitfraud infection. Superantispyware removes many smitfraud variants. If Super doesn't remove it all, then run the smitfraudfix.
