Your local Apple store has over 30 Macs of all shapes and sizes on the internet with full, unlimited, access (it's not uncommon to see Dell and HP laptop users just outside the Apple store using the stores on open, high-speed, wireless network for free). Ask the Apple Geniuses what they are using as virus protection for so many computers on such a publicly open system.

They will simply say "nothing" other than Mac's built-in firewall. This is exactly what our company does on a periodic basis. We take 5 minutes to chat with the lead "Genius" about their store's system. Our Macs are far from being publicly known or accessed, and If it's good enough for Apple's own computer's, it's good enough for ours.

There is absolutely no reason to bring the fear and paranoia of Windows users into your own home and business if you are running on Macs.

Go to your local Apple store and do whatever they do for protection... nothing! It Works!!
