Microsoft needs to make secure computing the cornerstone of the company, and the foundation of every product and service offering. In fact users are often uncertain if the file they are about to open is going to work as advertise, or is going to wreak havoc on their system. Even if users could accurate index the world according to these categories, it is very crude and not very useful. Systems need to function under the principle of least privileges, and in a large Intranet for example, there could very definitely be one or two servers with malicious trojans. Microsoft haters need to know MS is not going away, and need to get over it.
Industry giants die hard.
Bill Gates has liked to tell the story about when he first saw kit microprocessors, he thought IBM was toast. I remember the first 80386 processors being promoted as a mainframe on a chip and again IBM was predicted to be in deep trouble. What people did not realize was that as expensive as the big iron was, the investment in mainframe applications, Cobol code and business processes was infinitely greater. The point here is that Microsoft is not going away. Enterprises with a heavy investment in Microsoft desktops are not going to upgrade to Linux stations with KDE en masse any time soon.
