Hello, I am new to posting. I got this message shortly after downloading an infected file. Warning: Spyware has been detected on your PC. It has hijacked my desktop background. I've tried Adaware and Spybot search & destroy but nothing works. Also, there are popups warning me of an internet threat or some other problem. Also, it seems to have only affected one user account on my pc, not both. I appreciate any help that someone can give me. Thanks!
