There are four methods for updating virus definitions:
* The Virus Definition Transport Method (VDTM)
* LiveUpdate
* Copying an .xdb file
* Intelligent Updater
Read the following descriptions, and choose a method or combination of methods that works best for your environment.
The Virus Definitions Transport Method (VDTM)
The VDTM is a fully automated solution for virus definitions distribution, and is enabled by default between servers and their managed clients. With the VDTM, it is only necessary to update one server in order to update all computers in the network. The server gets definitions updates using LiveUpdate or an .xdb file, and then automatically distributes the definitions to each of its clients on the network. Read the following document for an overview and instructions:

LiveUpdate
LiveUpdate is a program that connects to a server, downloads the latest definitions, and applies the definitions to the computer on which it is running. You can run LiveUpdate from the Symantec System Center, or within Symantec AntiVirus. LiveUpdate can retrieve definitions files either from the Symantec server (which it does by default) or from an internal Web, FTP, or file server created with the LiveUpdate Administration Utility.
