Greetings --
Does the title bar of these pop-ups read "Messenger Service?"
This type of spam has become quite common over the past year or
so, 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 most definitely open to other threats, such as the Blaster and
Sasser Worms that still haunt the Internet. Install and use a decent,
properly configured firewall. (Merely disabling the messenger
service, as some people recommend, only hides the symptom, and does
little or nothing to truly secure your machine.) And ignoring or just
"putting up with" the security gap represented by these messages is
particularly foolish.

If you're using AOL, you'll either need to find a 3rd party
firewall that is compatible with AOL, or switch to a real ISP that is
compatible with the real Internet. This is because AOL is an on-line
content provider that ignores international Internetworking standards
in favor of its own proprietary products, and has deliberately made
its connection software incompatible with both WinXP's built-in
firewall and WinXP's Internet Connection Sharing feature. AOL's
proprietary connection applet is deliberately designed to preclude
your setting/adjusting any of its properties, to include
enabling/disabling WinXP's ICF and ICS.
Whichever firewall you decide upon, be sure to ensure UDP ports
135, 137, and 138 and TCP ports 135, 139, and 445 are _all_ blocked.
You may also disable Inbound NetBIOS (NetBIOS over TCP/IP). You'll
have to follow the instructions from firewall's manufacturer for the
specific steps.
You can test your firewall at:

Oh, and be especially wary of people who advise you to do nothing
more than disable the messenger service. Disabling the messenger
service, by itself, 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, if annoying, 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?
