I have a user who all of a sudden was getting a blank desktop with just their normal background on the screen. No programs will run through task manager. (Like if you run explorer.exe, nothing happens.)
If you reboot into Safe Mode, it loads, but then instantly reboots itself back to the blank desktop mentioned above. Even Safe Mode command prompt.
What virus exhibits this type of activity? And how can I get rid of it in XP without access to a command prompt?
