Before you reformat your computer (since thats a pain in the ass cause all of your files will now be all in one file then you need to put things back where you want them, and thats even if you hit restore keeping all your files). I dont know what happened to the thread yesterday, hopefully I didnt delete it by accident, at least your not banned as a spammer so thats good lol.
What anitvirus program do you use? Go here and download, update then run this program. Its free and safe.

I would also recommend Windows defender like Wil said. I never used that program but I've heard of it and will probably do that myself. Another one is spybot search and destroy. All of these are free (although they offer a better version that you need to pay for) and they will do a good job of getting rid of spyware. Antispyware programs like these are different than firewalls and antivirus programs where with those two you really don't want more than 1 as with intispyware its ok to have a few because one might pick up something the other doesnt and they usually dont interfere with one another.
Try these before you reformat and get back to us. dont forget to tell us what ur intivirus is.
