My point is 95% of the so called Windows exploits have always been caused by the stupidity of the users...Macs with their small share did not face that issue as most of that small share was informed computer users
With the Mac's growing (though slow it is growing) popularity with the ill informed, computer illiterate masses (Due to their market share a huge part of the windows users), Macs are gaining exploits on par with their growth in market share.
A stupid user is a stupid user no matter if they are using macs, windows, or a flavor of linux...and they will get exploited
