Wumply, I think you've gotten a bit confused here along with some others. To stop this spam you have to disable the "Messenger" in the Services menu (Control Panel, Administrative tools, Services). This has nothing in common with Windows Messenger or MSN Messenger which are "instant messaging" programs.

There is no need to block Windows Messenger in your Firewall.
