Microsoft is getting ready to offer Windows users a free antivirus product (code name Morro), something it should have built into one of its operating systems a long time ago. But, of course, Microsoft never makes things simple. So the big question is will Morro be worth the price?

Microsoft's goal is to offer the antivirus product as a hosted service, which is very different from what users have come to expect, especially when the word "free" is attached to the term "antivirus." After all, Grisoft and Avast have offered free versions of their antivirus products to PC users, and those free products are of the traditional download and install nature.
