Previously I Did Block Yahoo Messenger And Some Other Dangerous Services By Filtering TCP Ports. Unfortunately There Is Still A Way To Use Yahoo Chat!!! Portable Yahoo Messenger!!! Is There Anyone Here Help Me How To Filter Portable Yahoo Messenger?!

Yahoo messenger uses tcp 5100, tcp 80 and tcp 443.
You should block domain *.msg.yahoo.com,login.yahoo.com and *messenger.yahoo.com

Please refer to this article http://forum.lanctrl.com/viewtopic.php?f=10&t=329
