You're the Microsoft security admin for your company. While your real job is to take care of the security design and management of your company's computing infrastructure, your second job seems to be to take care of your family and friends computer's. This happens to all IT people -- whenever you see your friends or family, or go to a party, you become the "go to" guy for all sorts of computer problems. And as the "security guy", they will give you an extra pummeling of questions related to viruses, worms, trojans, and whatever the malware du jour happens to be.
If you need to duck out of these questions, Microsoft can help you with a Web page they've created for newbies. The security at home page has articles about Microsoft security that are written with the newb in mind. Lot of good advice that even the most Mac-minded Windows user can use to make his computer more secure.
