I found half a maggot in this Apple
I think the main problem lies with Apple and their fanbois.
I've lost count of the number of times I've met Apple users in my day to day working life who religiously believe that their sainted machines are invulnerable to malware of any sort.
Sure, we're mostly techy types in here and yes, we know when not to give a piece of software a password or agree to install something (although I will admit to clicking the wrong button once or twice, experiencing the 'ohnosecond') but the same old argument applies, you *have* to educate the lowest common denominator.
Preaching that a platform is invulnerable or worse denying the existence of an extant and demonstrable problem does not do that, it makes it *more* likely that the average 'I just wanna get on me facebook mate' user will do something stupid.
FWIW, despite some of my more rabid anti Apple/fanboi posts on here, I do like Apple computers I just despise the attitude of the company and the fanbois.
