1. My client has a network of 100 computers or so.

2. They have an antivirus solution running both at the gateway level and on each desktop.

3. They have disabled Yahoo messenger on all machines (basiically by dropping the connection attempts through the firewall) except for 8 machines.

They say that it is for security reasons. My question is how will blocking 92 and allowing 8 machines serve any better? Theorotically, even those 8 machines are good enough to allow any vulnerabilities, isn't that right?

Also, if not the Yahoo IM client provided by yahoo, are there any (free for commercial use) secure IM clients that will allow the rest of the users to talk to people outside the company that use yahoo also?
