Sorry about sending a blank email. There is a way to tell if you really do have a virus pirating your address book. A friend who works for Compaq (now HP, I guess) told me to add a fictitious address to my address book so that I will receive a mailer daemon if email is ever sent to that address. The email address that I use is 0!!! (that is a zero) and the contact name is Virus Alert. If I ever receive a mailer daemon for that contact I will know that someone has pirated my address book. Because the first character is a number and numbers always sort to the top of the list a mailer daemon on the first address in the message can, on some systems, stop the email from going out to anyone.
