Hello, I am looking for a product which either specifically disables or prevents the running of the various Instant Messenger programs ( AIM, Yahho, MSN, etc) and/or their installation. I have many clients with hardware based Firewalls (SonicWall) but it is not able to prevent these pests because they will morph into using port 80, the email port which I don’t want to disable. Any suggestions? Thanks,
Joe
