It's true, but it doesn't mean you have to buy anything.
Spammers are (mis)using a built-in Windows service that
was designed to transmit messages from the administrator
to users on a computer. It's quite easy to disable this:
stop the Messenger service (not the Messenger Application:
there is no connection between these two, except the name.
I'm speaking of a WinNT service, a special kind of program
that runs in the background). Of course, you may not want
to do it if you are actually using this service normally. In this
case, you should set up a firewall to block incoming connections
to the Messenger service.
It's one more annoying form of spam, but this one is really
quite easy to avoid. As far as I know (and, of course, provided
there is not security bug in the service), there is no real security
risk in this. (Of course, if spammers can access this service on
your computer, it's quite likely that one can access several other
unneeded server programs, possibly with nastier security
implications in some cases. Shut them down or set up a firewall).
Hope this helps.
