Windows XP logs on, then immediately logs off (even in Safe Mode)
Posted on 2009-04-14
I have a laptop here with Windows XP installed. It has been working fine for the past 2 years and a frequent virus scans / updates are run using Avast Home. I am also regularly running and updating SpyBot Search and Destroy.
A few days the laptop started to automatically log off as soon as I would log on. At that time I was able to boot in safe mode with networking which was when I updated my Avast program and definitions. I scheduled a boot scan which found 3 Trojans, then shut down.
Now I am not even able to boot in safe mode. I have removed the drive and attached it to a PC and am running a second full virus scan. The first full virus scan did not find anything, but when the drive was placed back into the laptop I am still unable to log on...even in safe mode.
Is there a permissions issue or file corruption that can en corrected? I'd prefer not to resort to a reformat.
Thanks in advance for any advice.
