Virus Protection Tip?

Got this from a friend and was wondering if it would work. This is what they said.
Here is what you do: first, open your address book and add a "New Contact" just as you would do if you were adding a new friend to your list of email addresses. In the window where you would type your friend's first name, type !000(that's an exclamation mark followed by 3 zero's). In the box where you would enter the email address, type WormAlert. Click Add then click OK.

Now, here's what you've done and why it works: The name !000 will appear at the top of your email list as entry number 1. This is the first email address a worm virus will find when it tries to send all of your friends a virus infected email. But because the 1st email address is invalid, it will be undeliverable, and the worm virus stops any further attempts to access your address book.

The second advantage of this little tip is that you will be notified when an email can not be delivered because of an invalid email address. You will receive an email telling you that your email to "WormAlert" could not be deliverd. If you get this message, you'll know right away that you've got a worm virus in your system. You can then take the appropriate steps to get rid of it. Just knowing that you even have a virus is half the battle.

Ok what do you think everyone will this work? Would like to have your input. Sami
