You get little messages? Popups? emails?
Greetings --
There are at least three varieties of pop-ups, and the
solutions vary accordingly. Which specific type(s) is
troubling you?
1) Does the title bar of these pop-ups read "Messenger
Service?"
This type of spam has become quite common over the
past several 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, such as
the Blaster Worm that recently swept cross 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. A free good
firewall you can get is ZoneAlarm.

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?
2) For regular Internet pop-ups, you might try the
free 12Ghosts Popup-killer from
http://12ghosts.com/ghosts/popup.htm, Pop-Up Stopper from
http://www.panicware.com/, or the Google Toolbar from
http://toolbar.google.com/. Also a good firewall can stop
these(such as nortons internet security).
3) To deal with pop-ups caused by any sort
of "adware" and/or "spyware,"such as Gator, Comet Cursors,
Xupiter, Bonzai Buddy, or KaZaA, and their remnants, that
you've deliberately (but without understanding the
consequences) installed, two products that are quite
effective (at finding and removing this type of scumware)
are Ad-Aware from
www.lavasoft.de and SpyBot Search &
Destroy from
www.safer-networking.org/. Both have free
versions. It's even possible to use SpyBot Search &
Destroy to "immunize" your system against most future
intrusions. Use both and generally perform manual scans
every week or so to clean out cookies, etc.
