About Program and Definition Updates
LiveUpdate obtains program updates and definition
updates for your computer by using your Internet
connection.
Program updates are minor improvements to your
installed product. These differ from product upgrades,
which are newer versions of the entire product.
Program updates are usually created to extend the
operating system or hardware compatibility, adjust a
performance issue, or fix program errors. Program
updates are released on an as-needed basis.
w
Some program updates may require that you restart
your computer after you install them.
LiveUpdate automates the process of downloading and
installing program updates. It locates and obtains files
from an Internet site, installs them, and then deletes
the older files and downloaded definitions from the
temporary folder after processing the updates.
Definition updates are the files that keep your
Symantec products up to date with the latest antithreat
technology. The definition updates that you receive
depend on which product you use.
