Not in my case. All the viruses sent, have come from Microsoft users. All. Doesn't bother my Macs, but my Windows machines squawk. My Macs rarely need rebooting. Windows, very often in order to recover from problems. Of particular concern is a brother-in-law who downloads to his PC from many questionable sites (movies etc.); all his emails carry viruses. I never get them from Mac folks.
That’s probably because all those Microsoft users download porn and free games laced with garbage. I don’t need any other programs other than Office and don’t visit crazy sites. Haven’t had a virus attack in over 5 years.
So I guess one could say that if one likes porn, doesn’t want to pay for anything, and expects the world to be polite, kind and courteous, by all means buy an unprotected Mac. You know, the one that runs the new crowned champion of security holes.
