The Story:
About two weeks ago my computer was seriously trashed by trojan, malware, and worms. It was pretty bad. It was a new system and I hadn't installed any anti-virus protection yet. So I bought myself a copy of BitDefender and went to town.
It found dozens of trojans, worms, etc. and cleaned them all up and then restarted my computer.
Since then I haven't been able to log on.
The computer boots and brings me to my log in page like normal. I type in my password and for a moment I see my desktop image and then BAM! I'm logged off. I've tried Safe Mode and the Admin account and the same thing happens there.
I went so far as to install a copy of XP on my slave drive and run a virus scan of the original drive from there. It came up clean.
So then I decided to run a Windows Repair... but the same thing is still happening.
My thought is that when BitDefender deleted one of the viruses it also deleted some critical registry file that deals with logging on. But I don't know.
Any and all help would be appreciated. Thanks.
