x2, and maybe some of the crap you downloaded is corrupt //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif. Might wanna check it out too before ya just reinstall and throw a bunch of crap back on //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif. Have you maintained the pc at all? have you ever defragged and all that fun stuffdosen't neccesarily get rid of all viruses. if you get a nasty bios virus ur just ****ed lol. but don't always resort to formatting, try tools like AVG free antivirus, adaware, and spy sweeper. you will be suprised at how much they help. you should be able to get them all at download.com
is it adblock? if so I'm bout to get it //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif.good choice on firefox. check out the extensions by going to tools - extensions.... get the ad plugin, i cant think of the name off the top of my head. but it's one of the best pop up blockers i've ever seen.
