Apple Recommends Mac Users Install Antimalware
I realize there will probably be a flurry of comments from Mac zealots letting me know that their operating system is still impervious, or at least that it is infinitely superior to the security offered by the Microsoft Windows operating system. Let me state preemptively- "don't shoot the messenger". It is the tribal elders from Cupertino who have issued the declaration. I am just relaying the news to increase awareness. If you wish to heed Apple's advice, check out the Mac Antivirus Software Reviews from About.com's Antivirus Software Guide, Mary Landesman.
UPDATE: A reader commented to note that the link to the Apple support note in question now leads to a dead page. Apparently, Apple has subsequently deleted their support guidance regarding antivirus protection for the Mac.

Comments
The Apple Support article link leads to a 404.
It leads to a dead page because the page was YEARS old. Apple took it down because of misleading articles such as this. They were initially telling people to just be cautious, as any computer user should be, windows or mac based.
That is partially true. They did originally issue the guidance to use antimalware a couple years ago, but the media didn’t dredge that nugget of wisdom from the past. Apple recently reiterated that guidance- which is what sparked the headlines and media attention. There was nothing misleading about my post. I simply stated a fact- that Apple had recommended that Mac users install antimalware protection. I think it is unclear why they took the page down. The guidance is still valid. The marketing people apparently had more clout than the security people.
