Creating a security policy prohibiting such activity followed by locking down the workstation to prevent users from 
installing unauthroized software is probably the best option.  

If you simply want to prevent users from using chat programs, then the next option is to block certain ports and IP 
addresses at the network boundary.  While users will still be able to download these programs, they will not be able to 
make a connection and chat.  There are proxy servers such as Bluecoat that will disable chat communications.  Blocking 
access at the firewall is a good idea as well.  Here's a link on how to block the most popular user chat programs at 
the firewall:

The list of IP addresses changes, but if you keep up with the changes it is a fairly effective solution.
