New Horizons in spam

Two days ago I got the following spam, which invites me to subscribe to a service that can send spam without using email. My first question is, is there any place I can complain to and my second is what is going on here? I am behind a firewall, so I suspect this cannot get to me.

Probably uses Messenger spam. It’s a new type that uses security holes in Windows (gee, who could imagine that?)

You can protect yourself in one of two ways:

  1. If you’re using XP, turn off the Messenger service (this is not Microsoft Instant Messenger). You’ll find it in the control panel under “Services.”

  2. Install and run either a firewall (http://www.zonealarm.com) or a pop-up stopper (I like Free Surfer).
