Keeping current with LiveUpdate
LiveUpdate updates all Symantec products installed on your computer, as well as its own program files. If you have Norton AntiVirus installed, LiveUpdate also updates the files used by Norton AntiVirus to keep your virus protection current.
Using your existing Internet connection, LiveUpdate connects to the Symantec LiveUpdate server, checks for available updates, then downloads and installs them.
If you have installed Norton AntiVirus in Mac OS X v10.1 and Mac OS 9 and want to update features in both versions, you must run LiveUpdate separately in Mac OS X and Mac OS 9.
About program updates
Program updates are minor improvements to your installed product, usually available for download from a Web site. These differ from product upgrades, which are newer versions of entire products. Program updates that have self-installers to replace existing software code are called patches. Patches are usually created to extend operating system or hardware compatibility, adjust a performance issue, or fix bugs.
LiveUpdate automates the process of downloading and installing program updates. It locates and downloads files from an Internet site, then installs them, and deletes the leftover files from your computer.
