Theyre running Windows XP and the problem is that today the laptop was crashing severly when any program was opened whilst the anti-virus was popping up saying that a virus has been found and forced them to reboot to the laptop.
Now at boot there is no option to choose a user, it only shows a blank username and password box in which none of the usernames work, an error shows saying that the domain is not available when any username/password is entered. Ctrl+alt+del does not do anything, safe mode entails the same problem and last known good config has no effect.
We're not sure if this problem is malware related or a windows error, any help would be greatly appreciated, thank you!
