Sony trojan problem

I played a CD on my computer that contained the Sony Copyright protection. Now I can’t get it off my system. Pest Patrol was the only one to pick it up. When i let the system clean, I was told to reboot and run again. When I rebooted, I Blue Screened. I was able to restore to a previous point, but of course the extra bagage came back.

Any ideas??
Thanks
