Apple Thoughts: Malware Blocker in Snow Leopard

"Apple's commercials may give the impression that Macs are virus-free but the company isn't taking any chances with the newest Mac OS X refresh."

I've never had a problem with malware or viruses either, but it is nice to know this is part of the package. Certain forms of malware have been found in some Mac products, albeit pirated ones, so it is good Apple is acknowledging the possibility, even if they are doing it below the radar.
