Keep Antivirus Definitions Up-to-Date (Mac OS; Windows)

Note: If you installed the software from this Virus website, the Supported Products website Leaving Penn's Virus website, or the PennConnect DVD Leaving Penn's Virus web site, it should have automatically run LiveUpdate to get the latest virus update files. If not, follow the directions below to manually run LiveUpdate.

How LiveUpdate Works

To keep your computer protected against new virus and malware threats, Norton and Symantec make updated definition files available from their servers through LiveUpdate. LiveUpdate connects to Norton or Symantec's web server, checks for and retrieves updated virus definition files, and then downloads and installs them on your computer. LiveUpdate can be run automatically at scheduled intervals or manually for immediate updates.

ISC Recommendations

Information Systems & Computing (Penn's central computing organization) recommends that you check your antivirus settings to make sure that automatic updates are scheduled to occur daily for both Windows and Mac OS. However, if you suspect that your machine has a virus, ISC recommends that you run LiveUpdate manually to immediately update your virus definition files.

Important: For an automatic update to occur, your computer must be turned on and connected to the Internet.

How to Schedule LiveUpdate to Automatically Update Virus Definition Files

Important: ISC has already configured the Norton software to update definition files automatically at scheduled intervals. Unless advised by your ITA or LSP, these settings should remain as configured.
