The computer repair store is telling me that I have a virus based on what I described above that occured after installing AVG update. I have Dell E521, Windows XP Operating system. I run an AVG scan daily and have never had any problems with my computer prior to this incident, nor have I had any virus activity reported after the AVG scan. Is it a virus or not?
After running update computer gave blue screen error after manually shutting off and on - Unmountable Boot Volume - the instructions said to restart in Safe Mode and uninstall but can't restart computer at all - when I select Safe Mode I get a screen full of messages that say "multi disk rdisk partition..."
