corrupted error after log off

my father has windows xp sp2,uses aol,when he log off he gets an error that
his computer is corrupted and if he trys to reboot his computer will not turn
on. Any suggestions? Norton, Mcafree and Spyware does not detect a virus.

Make sure you have the LATEST VIRUS UPDATES, mine crashed BIG TIME, last
week from a NEW Virus Backdoor.barbew.L and you can go to Symantec and
read about it, it was discovered in Nov and if you don't have UPDATES will
NOT detect it and Norton's can NOT delete it.
During my re-install I picked up another S.O.B. W32.korgo.ab and it
is proving to be a real S.O.B. it is a very new one as well.
I am on my work computer, trying to seek info. Not my infected one.
