Just thought some of you running Windows on your Mac should know Microsoft is now offering their anti-virus solution for free. I've been beta testing it for awhile, and I have to say it's really light weight and unobtrusive (no stupid pop-ups, etc). Try it out if you need anti-virus. I believe it's for XP (32-bit) and Vista/7 (32 and 64-bit). http://www.microsoft.com/Security_essentials/ Why didn't they do this years ago instead of fostering a market of third-party market anti-virus solutions?
