Do not even read the pop up from AntiVirus2008 and if possible, protect your credit card information. They somehow got mine and tried to charge me for services I never even inquired about. Thank god I have a prepaid credit card and I will not put anymore funds on it. I also already had mcafee security, so I know I didn't have any viruses on my computer, but it was slow and for a while I couldn't do anything until I unplugged my computer and it was gone, finally. Total scammers and thieves!
