I posted an entry several minutes ago. while on your site I was reading other posts. I was getting pop ups about security software and virus software. suddenly my laptop screen went blank except for screensaver. I restarted and the Security Total had taken over the laptop. I can't run your malware scan from the desktop or from a flash drive. can't open task manger, registry editor. or internet. I was running a wireless connection with windows and mcafee firewall. Windows updates is disabled (problem before this happened) can't enable. please help. Son needs laptop for college next week.
