The NTBUGTRAQ list had some recent postings on this topic, with links to two
articles in The Register. One article tells how to make MSN Messenger appear 
on the Add/Remove Programs control panel, so you can uninstall it cleanly. 
The other tells how to disable MSN Messenger without removing it. Neither 
option is bullet-proof, because it is only a matter of time before MS 
releases a patch that re-installs or re-enables Messenger.
