If the Messenger service is stopped, messages from the Alerter service
(notifications from your antivirus software, for example) are not
transmitted. If the Messenger service is turned off, any services that
explicitly depend on the Messenger service do not start, and an error
message is logged in the System event log. For this reason,
Microsoft recommends that you install a firewall and configure it to block
NetBIOS and RPC traffic instead of turning off the Messenger service.
This particular "sales method" is strikingly similar to the "protection"
rackets offered to small businesses by organized criminals. Yes, it's a
scam; no reputable business would need to resort to extortion. Particularly
since they're trying to sell you a type of protection that is already
available to you free of charge.
This type of spam has become quite common over the past few months, and
unintentionally serves as a valid security "alert." It demonstrates that you
haven't been taking sufficient precautions while connected to the Internet.
Your data probably hasn't been compromised by these specific advertisements,
but if you're open to this exploit, you may well be open to other threats.
Install and use a decent, properly configured firewall. (Disabling the
messenger service, as some people recommend, only hides the symptom, and
does nothing to secure your machine.) And ignoring or just "putting up
with" these messages and the problem they represent is particularly
foolish.

Oh, and be especially wary of people who advise you to do nothing more
than disable the messenger service. Disabling the messenger service is a
"head in the sand" approach to computer security.
The real problem is not the messenger service pop-ups; they're actually
providing a useful service by acting as a security alert. The true problem
is the unsecured computer, and you've been advised to merely turn off the
warnings. How is this helpful?
Equivalent Scenario 1: Somewhere in a house, a small fire starts, and
sets off the smoke alarm. You, not immediately seeing any fire/smoke,
complain about the noise of the smoke detector, and are advised to remove
the smoke detector's battery and go back to sleep.
Equivalent Scenario 2: You over-exert your shoulder at work or play,
causing bursitis. After weeks of annoying and sometimes excruciating pain
whenever you try to reach over your head, you go to a doctor and say, while
demonstrating the motion, "Doc, it hurts when I do this." The doctor, being
as helpful as some of your respondents, replies, "Well, don't do that."
I'm beginning to think that the people deliberately posting such bad advice
are hacker-wannabes who have no true interest in helping you secure your
system, but would rather give you a false sense of security while ensuring
that your computer is still open to exploitation.
