Keeping your Norton AntiVirus definitions up-to-date (Macintosh)

To keep your computer and your information free from new virus threats, Norton makes updated virus definitions available from its web site on an ongoing and as-needed basis. Using Norton's LiveUpdate feature, you can automatically install these updated virus definitions on your computer thereby keeping your anti-virus software up-to-date. There are two ways to use LiveUpdate to get the updated virus definitions files. You can configure LiveUpdate to run automatically or you can run it manually. ISC recommends that you configure LiveUpdate to run automatically. However, in case of a virus emergency and you need to get the most recent virus definition file, ISC recommends that you run LiveUpdate manually. ISC provides information about new and existing viruses on its Virus Alerts page.

Important: For an update to occur, your computer must be turned on and connected to the Internet by an office, ResNet, or modem connection.

How to run LiveUpdate automatically

You can schedule LiveUpdate to run at regular intervals. In this mode, LiveUpdate automatically connects to Norton's web server, retrieves the updated files, and downloads and installs them on your computer. Having the updated virus definition files means that your computer will be scanned for the most recent viruses, without the updated files your computer is not protected from new viruses.

To schedule LiveUpdate to run automatically, do the following:

1. Open the Norton AntiVirus control panel.
2. Click the "Live Update" button.
3. Click the "Schedule Future Updates" button.
4. Click "New".
5. Type a name for the scan and then click "OK".
6. Use the drop down menus to identify "Event Type", "How Often", and the time that you want LiveUpdate to run, and click "Done".

Remember, your computer must be turned for the scheduled update to take place.

How to run LiveUpdate on demand

To run LiveUpdate anytime manually, do the following:

1. Open the Norton AntiVirus control panel.
2. Click the "Live Update" button.
3. Click the "Update Everything Now" button.
4. Click "OK" If you have the most current virus definition files, the message "No update is necessary" will display.
5. Click "Restart" when the update is complete.
