Hi. I'm thinking about getting a new mac (G5) for the office and the one question that's come up so far that I haven't been able to answer is that of virus protection. I've read about McAfee Virex but I can't find any info for it on McAfee's website. Does it come free with OS X or is purchased separately or what? Also does the Virtual PC software help OS X to better integrate in a Windows environment? I'd appreciate any and all advice anyone can give. Thanks, Chris.
