--------------------------

If you are running version 7 of the Pix software, you have more options to stop IM traffic.

• Introduces new inspection services to detect and optionally block instant messaging, peer-to-peer file sharing, and other applications tunneling through Web application ports

• Blocks popular instant messaging applications such as AOL Instant Messenger, Microsoft Messenger, and Yahoo Messenger

• Stops peer-to-peer file sharing applications such as KaZaA and Gnutella

• Thwarts tunneling applications such as GoToMyPC
