Hi, my 3 ghz desktop got infected with virus. Even though i had norton av, the winXP sp2 does boot till welcome screen. But when i try to enter the password for user as well as admin...the os does show its loading the settings and at that very instance the os logs off! I even tried accessing system restore, but the os again logs off. How can disable the welcome screen? Or is there any other way i can access my os for backup? - eric
