Log on problems

[Guest]

Hi, Im running Windows XP sp2 on a HP pc. I discovered a virus on my pc, cant
remember the name, but it infected mostly .exe files. I loaded Panda
anti-virus but about three-quater way through the scan it the program stopped
responding and i closed it using end task. Also, while scanning it said some
files could only be disinfected by restarting the pc. I restarted my pc later
and then i tried to log on to my account with my password. Windows starts to
load my settings but once its loaded it immediately logs out again and goes
back to the welcome screen. The same thing happens with the other user
accounts. I tired booting up in Safe mode and Last Known Good Configuration
but this doesn't help either, the same thing happens with the Administrator
account.

I think the virus may have damaged some Windows files. Is there anyway I can
fix this problem and repair Windows without having to reformat my pc and
wipping out all my files? PLEASE HELP! THANX

Before you do anything more get hold of a Knoppix live CD (
http://www.knoppix.org/ ), boot your machine with this and copy your data
files, bookmarks, email, etc. etc. to either an external HDD or USB keys. If
this is not possible put the drive in another computer as a slave or as a
master on the secondary ide bus and copy your important files over.

Once you date is backed up then you may be able to do a repair install :-

However, you may be better off reformatting your machine to get rid of all
traces of the virus as it probably caused corruption in other software not
just windows.
