The article started off:

an internal feature in personal computers using the latest versions of Windows, not to be confused with the MSN Messenger Internet chat program -- are being mercilessly exploited by spam "pop-up" advertisements.
My "Duh" was the very next message, and it was correct - firewall the bloody ports - you should never have them open to the world anyway!!!!!!

This spam starts with a connection to port 135 so sites with firewalls that block incoming connections to the Microsoft networking ports (135, 137-139, and 445) are immune from this spam.

The upshot: I wasn't confusing anything..... You have allowed the meanderings of the thread to confuse yourself by the look of it..... Old age?????

You've been "testy" of late old chap..... Everything ok?
