I'm trying to restore a Presario 6000 to factory default. It's infected and the anti-virus program won't remove it. I've tried to do a system restore but I get the message that it's infected to. She tried loading norton 2010 anti virus but she can't get online to activate it. So, while norton tells her about the virus, It won't remove it until it's activated. I get the message "worm32.netsky detected" . So I figured if I just do a system restore to factory default using the online partition info it could take care of the problem. However, I can't get the computer to use the restore function. I've tried hitting f10,f11,f12 on start up with no luck. Anyone with suggestions?
