Product manual

As the Smart Definitions are of considerably smaller
size, it results in lesser download time, lesser
installation time, lesser boot time, and lesser memory
consumption. It also occupies lesser amount of disk
space as compared to the full set of virus definitions.
Therefore, Smart Definitions result in faster
performance of your computer.
Norton Internet Security checks the SmartDefinitions
option settings during each LiveUpdate session. If the
option is turned on, the Smart Definitions are
downloaded and installed. If the option is turned off,
all of the virus definitions are downloaded and
installed.

About running LiveUpdate
You should run LiveUpdate as soon as you install
Norton Internet Security. Some Symantec products
run LiveUpdate automatically to keep your protection
up to date. If you do not use the AutomaticLiveUpdate
option, you should manually run LiveUpdate once a
week.
In addition to the definition updates that Automatic
LiveUpdate downloads, the product uses streaming
technology to download the latest virus definitions.
