Symantec Client Security Version 3.1 (Windows Firewall)

Symantec Client Security includes antivirus and firewall programs that protect your computer against viruses and unwanted network intrusions, including Trojans, worms, spyware, and pop-up windows.

System Requirements

• Windows ME, 2000, or XP
• 42MB or more of disk space on your local hard drive
• Symantec Client Security version 3.1 from USC's software download page

Installing the Correct Version

ITS provides two versions of Symantec Client Security. Choose the on-campus version if your computer is constantly connected to the network and is never powered off. Choose the off-campus version if your computer is not constantly connected to the USC network and is powered off regularly.

On-Campus Client

• Virus definitions are automatically and regularly updated through a constant connection to ITS's virus definition server.
• New firewall definitions should be downloaded from Symantec using LiveUpdate.

Off-Campus Client

• New virus and firewall definitions should be downloaded from Symantec using LiveUpdate.

Pre-Installation Recommendations

When you install the Symantec firewall, the built-in Windows XP firewall will be automatically disabled. ITS recommends that you uninstall all other firewall programs, and all antivirus programs on your computer before installing Symantec Client Security.

Installing Symantec Client Security over previously installed versions of Norton or Symantec antivirus or firewall programs (other than the Windows XP firewall) could cause software to fail, and may require you to reinstall Windows. If you would like further information on how to uninstall your previously installed Norton or Symantec program, see Symantec's Support Site and search for your program.

Note: ITS does not support altering the default configuration of Symantec Client Security.

1. Download the appropriate on-campus or off-campus Symantec Client Security 3.1 software from USC's software download page.

3. Click Next. The Symantec Client Security Install Shield Wizard displays.

5. The Setup Type dialog will display. Select Complete and click Next to continue.

6. Click Install. The wizard installs Symantec Client Security.

You will be prompted to run LiveUpdate, which will install client updates as well as virus and firewall definition updates. ITS recommends that you install these updates.

ITS has pre-configured Symantec Client Security to automatically block several problematic ports, and to automatically open only those ports necessary for daily computer use. For a list of open and blocked ports, please see the configuration details section of the Firewall FAQ page.
