Well I seem to remember that this entire argument was started because you seemed to think antivirus was unnecessary because there has never been any malware, now I've given you a document from Apple stating that in actual fact Antivirus is recommended.
I see you failed to address my point regarding security updates via the software updater. If there has never been any malware why would Apple need to address issues on a regular basis? But if you wish to rest your case on such poor defence then feel free.
Here's a recent security update Apple have issued:
http://support.apple.com/kb/HT4435
You'll notice the various fixes regarding "arbitrary code execution" clearly illustrating that malware exists and can take advantage of services that run on Mac OSX. In fact the only reason they patch these things is because people have taken advantage of them.
Not even Apple deny the existence of malware on their platform simply because it's impossible to create a 100% secure system, malware does exist for Mac OSX, just because you haven't been affected does not mean that it does not exist.
You've been given several resources illustrating that malware exists, if you wish to remain blinkered then feel free, just don't give your biased opinion as fact to others.
Clearly you seem to think you're getting a better product because you spend more, are you aware that most servers out there providing internet services run on Linux or BSD? Both of which are completely free, a prime example that a more expensive product does not mean a better product in the field of operating systems. I run a free operating system and I guarantee I'm able to achieve much more with mine than you're able to with Mac OSX.
It's simple Apple have an incredibly good marketing department and you seem to be unable to distinguish between fact and marketing spin.
