Open Ports
When you install Symantec AntiVirus for Windows Vista, the installation process automatically configures the Windows Firewall to allow exceptions for Symantec AntiVirus processes that require access to your network and the Internet. If your managed clients run third-party firewall software, and you want to manage these clients through the Symantec System Center, you must open the following ports:

Port	Function
TCP 2967	Allows communication between the Symantec System Center and Symantec AntiVirus clients and servers.
TCP 139	Allows remote installation of Symantec AntiVirus clients.
UDP 38293	Allows Discovery of Symantec AntiVirus servers that manage your clients.

You should permit Rtvscan.exe on all computers, permit Pds.exe on servers, and permit the Symantec System Center to send and receive traffic through your firewalls.
