You're welcome ^_^ You have spyware, and you need to download spybot search and destroy
http://public.planetmirror.com/pub/s...spybotsd14.exe that will get rid of them

Exit all the popups that come up on your computer immediately, even if they say they will get rid of spyware and viruses. This will just cause more problems. Run Ad-Aware, Spybot Search and Destroy, AND any other spyware removers you like to use. They will all find stuff the others missed.
And yeah, it's widely known that best buy is horrible.
