Sophos are saying there is more threats to the Mac, which is true, although most are still social engineering ones, it looks for both windows and mac malware and will remain free because they love macs so much ::) I agree the day is fast approaching macs will need it, but not for the love of them like sophos says, great business model though ;D
;D
And if it anything like the coporate version its prob not worth having.
