picked up trojan horse that I thought I had cleaned off but obviously not fast enough.

computer would boot FINE, but at XP log-in screen, you can SELECT a user and type password, then it takes you right back to log-in screen.

booted the machine in safety mode and ran eTrust with week old data file. found bad files, deleted those...but also identified userinit.exe file as corrupted without being able to identify a fix or the virus. left those files in quarantine.

now, can not log in even in safety mode...any suggestions other than rebuilding?Do you have the Windows CD?Will have on Sunday when I return homeOk. When you can, perform a Repair Install.

(None of your files will be lost)Okay...FOLLOWED instructions as WRITTEN for repair install. Everything seemed to work fine, but when completed still have same problem. Get to login screen, let's me enter password and then says logging off. Any other ideas?
You've performed a repair install yet you still cannot log in?

What about Safe Mode?
