NAC – Installing and Configuring Antivirus

To protect the campus network from the spread of viruses and malware, we require all computers to have Antivirus software installed. While you may use the software of your choice, UNC provides free copies of Symantec . Besides simply running the software, it must be enabled to actively monitor your computer and it must stay up-to-date. Through automatic and manual scans, Antivirus software monitors the data on your computer and notifies you of any potential virus infections.

Please note that if you’re unable to follow the instructions below it may be because you’re already infected with a virus and it is preventing you from installing, updating or enabling Antivirus software. If this is the case, simply contact us for support.

Installing Antivirus Software from UNC

1. Go to

2. Scroll down to Symantec and follow the instructions to download the software to your computer.

Note: If you don’t know if you are running a 32 bit or 64 bit version of your operating system, click Start, Right-click on Computer, and select Properties.

3. After downloading the software, double-click the file to install it on your system. If you have any old copies of Antivirus software installed, you should uninstall them first by choosing the appropriate option in your Control Panel.

Updating Antivirus Software

As new viruses are released, your Antivirus software must be updated with the latest virus definitions to stay protected. The Symantec product that UNC offers does this automatically. You can manually run the software and then choose Live Update to verify that you have the latest definitions.

Enabling Active Protection

Antivirus software should be designed to actively monitor files on your computer so that it may stop a virus from spreading immediately, as opposed to catching viruses during a weekly scan. By default the UNC Symantec software is configured to automatically protect your computer, but if it is disabled, simply open the application and modify the settings.

3rd Party Antivirus Software

You are also welcome to use 3rd Party Antivirus Software. Just be sure the software is properly configured to automatically update virus definition files and to scan your computer.
