In all truth, the primary reason for Apple's escape from infestation is one due to far lower market share. It is more effective to build code that will attack Windows based computers than it is to develop code for an Apple OS environment.
If you are not familiar with computer malware, much like any bacterium or virus, it is suited for a particular species. Thus a virus that gives your pussycat leukemia, would not cause you or your fellow humans the same problem.
A computer based malware such as a virus is much the same. A ILoveYou worm does its damage by utilizing VBScript on Windows based computers. This worm is unable to function in a Apple enviroment because the code that the worm was developed in is Microsoft Visual Basic and requires a Windows based registry to infect. While it is certain that millions of Apple computers received the ILoveYou worm, none was infected because this particular malware was not developed to infect an Apple.
Now getting back to my point, by taunting the very hackers which develop malware, Apple is inviting them to code specific malware infections for the Apple OS. Staying under the radar has protected Apple from the onslaught, but I am afraid that this situation will only change as Apple market share increases and the company taunts the very people that create malware.
