There is a difference between VIRUSES and MALWARE!
Macs do NOT get viruses. That is simply a true statement. And as far as malware goes, there have only been a small handful ever that were not even very harmful.
I am so sick of stupid PC and Micro$oft lovers ripping on Apple and their marketing. They are simply stating the truth. And NO this is NOT anti-virus software in Snow Leopard. Get educated you morons!
This is merely good preemptive implementation just in case, something that Micro$oft knows nothing about. They just do things like crap and make a huge mess and then try to clean up the after math. There is nothing to worry about. Apple is just continuing to protect its users before there are problems.
Thanks Apple!
SCREW YOU ALL PC and Micro$oft lovers!
