How to protect address book from viruses

[WHODOER]

I got this in an Email from a friend and would like everyone ideas about this, if it will really work or not.

HOW TO PROTECT YOUR ADDRESS BOOK!

I learned a computer trick today that's really
ingenious in its simplicity. As you may know,
when/if a worm virus gets into your computer it
heads straight for your email address book, and sends
itself to everyone in there, thus infecting all your
friends and associates.

This trick won't keep the virus from getting into your
computer, but it will stop it from using your address
book to spread further, and it will alert you to the
fact, that the worm has gotten into your system.

Here's what you do: first, open your address book and
click on "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 in AAAAAAA. Same in space
labeled screen name.

Now, here's what you've done and why it works: The
"name" AAAAAAA will be placed at the top of your
address book as entry #1. This will be where the
worm will start in an effort to send itself to all your
friends.

But, when it tries to send itself to AAAAAAA, it will
be undeliverable because of the phony email address
you entered. If the first attempt fails (which it will
because of the phony address), the worm goes no
further and your friends will not be infected.
Here's the second great advantage of this method: If
an email cannot be delivered, you will be notified of
this in your In Box almost immediately. Hence, if
you ever get an email telling you that an email
addressed to A could not be delivered, you know
right away that you have the worm virus in your
system. You can then take steps to get rid of it! Pretty
slick huh?
If everybody you know does this then you need not
ever worry about opening mail from friends. Pass this
on to all your friends
