" dear sirs,
i'm prompted for my password when logging on to windows just as usual, then i enter my password and windows starts loading, i can hear the start up tune and i can display my desktop bagground for a few seconds, then windows logs off automaticly and i can hear the logging off tune, and i am back at the log on to windows prompt, this repeats itself in eternity, the same thing happens, when i try to start my pc in safe mode or when i shut my pc down and start it up again, i have windows xp professional, please advise
thank you for your replies, but i feel a little bit misunderstood, so i post a new topic. i think my last topic was closed...
...anyway, i havn't forgotten my username or password, they're both perfectly correct, there's something wrong with my pc, i was installing norton internet security 2009, when i was attacked by some kind of virus, not vundo, so i ran malwarebytes anti-malware and it detected and deleted about 16 infections, including vundo, after this i continued with the installation of norton is 2009, and to complete the installation i restarted my pc, after this i can't log on to windows anymore. i have been infected with vundo for about a week, and i am not sure whether it was fully deleted by malwarebytes anti-malware, because i had not been able to delete it previously, also with norton is 2009.
