It's only a matter of time until someone sues Microsoft for its antispyware offering, currently named Windows Defender and in beta. Some spyware or adware vendor is going to sue them for singling out their company. Who is Microsoft to say that their spyware shouldn't be allowed to run on peoples' PCs? They're going to make it into an antitrust lawsuit, and it will be dragged out for years and years, and in the end, nothing of value will be accomplished, except a lot of money will change hands. Mark my words.
