If there are people you'd like to keep on file, but don't want to risk sending accidental e-mail to them, copy their e-mail address to the "other" section of the person's entry in your Windows Address Book. Then delete the e-mail address from its regular location. You'll still have the address on file if you need to refer to it, but you won't accidentally send out e-mail to the person. I think this would also eliminate the chance of a worm or virus sending e-mail to that particular person.

People who send and receive lots of e-mail are bound to pick up a virus or worm along the way. I think they have a responsibility to be aware of that, and to take special precautions to protect others.
