Profile loads, and then logs out

[Nobbygas]

I think I may have a virus, but I cannot get onto the system to find out.

When my XP system boots, it asks me for a user password. During set-up two
years ago, these passwords were left blank. If I try to load my user account,
or the Admin account, it says the user is logging in, but logs it straight
out again.
I have tried using a couple of tools which gave me access to these accounts
during the boot phase, and they tell me that the passwords are blank, but I
still cannot log onto the system. Any clues?

If they were left blank then press the enter key.

Did you get an answer that worked? - I have the same problem.
I am afraid of losing all my files if I reinstall XP
