WHY? Norton AntiVirus relies on up-to-date information to detect and 
eliminate viruses. One of the most common reasons you may have a 
virus problem is that you have not updated your protection files since 
you purchased the product.

Symantec provides online access to these new files, called virus 
definitions files, at no charge every month. You need to update your 
virus definitions files monthly.

From Windows, use a modem or Internet connection to let

information, see Symantec Service and Support Solutions at the end

because it automatically downloads the proper files and installs them on 
your computer. You can get virus protection updates anytime by clicking 
the LiveUpdate button.

2. In the Norton AntiVirus main window, click LiveUpdate.
