[23 March 2012] Seems I had this rant in my draft
In my humble opinion, it is absolutely necessary to have basic antivirus protection installed on your Mac regardless of the number of virus currently out there for the Mac.

In short its about being prepared
No personal computer exists in a vacuum. As elegantly designed as Macs are, a connected world means that their popularity attracts the attention of malware writers and virus engineers. Not only can malware and other threats attack the Mac OS X platform directly, but Macs can also serve as a carrier of Windows or Linux-based threats. Network shares, email and removable media like USB keys are easy ways for multiplatform malware to spread undetected. Additionally, third party applications which are not consistently patched and updated, are prime targets for hackers to gain control of user systems.
