Well I don't know - I switched across to Mac OSX about 5 years ago. In all those 5 years, I have had absolutely ZERO virus/whatever problems, and I don't run any other anti virus programs or whatever.
Four Mac OSX devices here - two iMacs 24 " and 27 " quad core, and two MacBook Pro laptops, both 15 ". Not one iota of a problem.....zero/zilch/nada/lutho (zulu). And my Apple Macs are connected to the internet 24/7.
Oh....I forgot, and I have a quad core Apple MacMini....no problems in the slightest there either.
Maybe the guys having problems are permanently hooked into the porn sites
