i went to a site to download software, and every since that download, I have had problems with my computer. My computer is slow on the net, i keep getting pop up ads. so i downloaded spysweeper--didn't fix it. removed that and downloaded spybot--didn't fix it. removed that and downloaded bps spyware remover, and this has not fixed the pop up problem either. now i dont want to use just a pop up stopper because i have not had this problem before, and i just dont want to cover the problem up, i want to remove whatever is causeing the popups, because when my homepage loads, i get an advertisement page to load as well. now, i am running windows xp professional and i had already disabled the thing that stopped messages popping up. also, i checked in regedit and its not ezula, and i dont particularly notice anything different in there, but thats not to say that it is not. but what could be causing these popups all the sudden and how do i remove the problem, not cover it up with something like popup stopper. also, i run norton antivirus 2004, and of course it is up to date. please help me, its getting very annoying.
