“[Long description of the technique adding a bogus email address to
the beginning of your address book omitted] … But, when it tries to
send itself to AAAAAAA@AAA.AAA 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.”
Will this work Leo?
Flat out, no qualifications, no. Does no harm but does no good.
OK, it might do some harm, in a backhanded way.
The theory is that malware which sends email does so by using your address book, and as it walks through your address book it will stop trying as soon as it encounters a failure to send. The technique then is to create an entry alphabetically first in your address book that any malware would encounter immediately, causing it to fail and go no further.
The theory is wrong.
Most malware no longer bothers with your address book, so doing anything to your address book is not nearly as effective as you might think.
Any malware that does use your address book may or may not do it in alphabetical order.
Any malware that does use your address book isn’t going to stop on a single error. It’s going to plow through no matter what.
Perhaps there was a virus that behaved this way many, many years ago, but malware has gotten very sophisticated. Simplistic solutions like this simply aren’t going to have any noticeable effect. You’re just as vulnerable before as after.
Speaking of vulnerable, I did say it might do some harm, didn’t I? Here’s how…
You may think that you’ve taken a step to protect yourself when you haven’t. You may then think you don’t need to take additional steps, when in fact you still do.
You might fool yourself into making yourself a bigger target.
Don’t do that.
There is simply no substitute for taking the steps necessary to protect yourself from malware. The “usual litany”:
The list could go on, but those are the basics.
And you’ll notice that putting a bogus entry in your address book isn’t on it.

OK so adding the bogus email will not stop the malware, but the email server will bounce the email back, which indicates that you have a problem?
But if it does try to send it out, won’t you then be notified that it failed? I did this too, and then as a trial I sent it out, only to have my email program (outlook) immediately send me a notice that it failed. So it seems like it would work at least as a notification that something is wrong. Sometimes people you know get infected and send something infected. Just a thought.
