Tech Clinic / Trojans Reproducing After Being "Deleted"
« on: June 22, 2008, 11:32:36 PM »
My Windows XP has gotten hit by a monster virus of some kind this weekend: In a matter of seconds it wiped out most functions. It won't even shut down apart from using the power switch.
I was finally able to run an Avast boot-time scan in Safe Mode, which identified & deleted several Trojans. But the files keep reproducing:
In the System Configuration Utility, in Startup, I repeatedly uncheck the affected files:
C:\WINDOWS\System32\drivers\svchost.exe
C:\Documents and Settings\user1\svchost.exe
C:\Documents and Settings\user1\Start Menu\Programs\Startup\userint.exe
When I reboot, the box pops-up to indicate the unchecked-changes were made, but when I open msconfig Startup again, they're are all checked again. (I know these appear to be system files, but they never showed up before the computer got infected).
I've run all my antiVirus programs and Googled for other information, but the problem remains. (Also, System Restore has been wiped clean).
If anyone can shed some light on this it would be greatly appreciated!
