Well obviously. Im not surprised they have started to "aim" at it now.
This article is stupid.
The Apple computers don't use anti-virus protection software
they forgot to add "By default" - of course you can run AV on a Mac, it's just there is no point yet.
Have you ever installed Windows? That doesnt come with AV either!! Should we panic now? No, you go download AVG or Norton, or whatever.
The key difference between the OSX and Windows is that on the latter programs can install with no intervention of the user.
As you may have seen with the recent MacDefender trojan flying around, you need to enter a password for it to install. Don't enter your password, problem solved.
Common sense computing prevails over malware.
