XP Login Issues

[ajd]

I have a client computer that was infected with a virus.
The person then scanned the PC and deleted many unknown
files. Now, whenever anyone logs in (by just clicking on
the username w/o a password) they immediately get logged
out, automatically. Any ideas?

Please Help!

If you can't logon at all I would run a repair on the OS.
