ONC,
No. I disagree. I run a free anti-virus and have for years. Since XP, PCs have gotten a lot better. I have two desktops that are 9 & 10 years old and run fine. I even have Windows 7 on them, as they meet the parameters for W7. (barely) These desktops cost me half the price of a store bought as I built them. So, for $400-500, they have shown their value. BTW, macs are not impervious to viruses. They used to be, but only because a limited number of people actually bought macs. So, the virus writers ignored the mac OS. That isn't the case any more. If you're using a mac and NOT running an anti-virus, you're asking for trouble. My newest PC, which is now 6-8 months old will run circles around most macs. (it's tough to put an age on my newest PC because it took me a few months of parts buying)
