I have Avast 4 Home. I had it running for about 1 month on XP machine I’d had about 1 yr. Something happened not sure if was a Virus, Microsoft Patch, or what (ie kids). Every time I turn on machine I get login and about 10-15 sec later machine locks (HD and Mouse, etc stop). I can type in my password and can see the desktop, or if I don’t log in it locks up at the login screen. I tried Safe Mode and only one that works is the command prompt. I ran CHKDSK and it made no corrections.
How can I force AVAST to do a pre OS Boot Scan from the command prompt ?? I need to rule out a virus. I don’t want to OS reload unless I have to. Any other suggestions would be helpful.
