"Most Mac users gaze on smugly as reports of each new Windows security crisis break. And they have good reason - research from Sophos PLC showed that 68 viruses have affected the Mac while 97,467 have affected Windows. Of those 68, most are a decade old or older and don't directly affect OS X," Digit Magazine reports.
