I downloaded something of the internet and it connected to keygen even though I wasnt downloading that. So as soon as I found spyware was on my computer I run norten and Spysweeper. But my computer kept shutting down. So I clicked search and searched keygen. I then deleted all of the keygen files and deleted everything spysweeper picked up. I went on today and I still have the problem. I try to download the adware and search and destroy stuff but it keeps shutting it down half way through. I really dont know what to do. I cant get any new virus things because its not letting me and I cant find it on spysweeper.

Try AVG's free antivirus program:
