Bill D, see the F-Secure site - kak fixes. It may focus on Outlook to send itself, but any program that opens it as html will activate it.

I still have an e-mail with the kak worm in it, and my virus detection program (updated last on Nov 23) does not detect it. It did detect the virus once it had been activated and created the files it's known to create. The anti-virus detected those files, not the Active-X script in the e-mail that creates them.
