What Microsoft currently calls its "Security Essentials" suite is really, frankly, a scam. At least, in the post-Windows XP world. How they pulled the wool over people's eyes is brilliant, and I don't blame them for the approach. However, calling it any sort of security "essential" is borderline false. I can't complain since they don't charge for the product, but I felt it necessary to divulge things you may need to know about this so you can make informed decisions.
