Scott if your running win 2000 or xp and the system restore is on you will have to shut down the system restore so your antivirus software will then have access to it as while it is running no virus checks can be done on it. Shut it down and reboot system then run your antivirus then you can restart the system restore if you like. It seems most trojans these days like to go there and it is impossible to remove them unless you do the above. I have done this several times and works great for me
