Just installed Symantec Anti-virus Corp Ed V9. I had uninstalled V8 before installing V9. Already on my system was Norton Ghost and System Works 2003. Live Update would not work on any of the Norton (Symantec programs). Turns out that the live update used for V9 is different than all previous Live Updates and conflicts with them.
The solution is on the Symantec site (http://service1.symantec.com/SUPPORT/sharedtech.nsf/docid/2000100610540413?Open&src=&docid=2000041710560048&nsf=ent-security.nsf&view=docid&dtype=&prod=&ver=&osv=&osv_lvl=). The old Live update has to be uninstalled and a new one compatible with the enterprise app is also compatible with the other apps. So be aware of this potential problem.

Also if your running Outlook XP & update from AV8 to AV9 the plugin for the email scanner will not work properly & it will annoy you with popup messages about it.

well? is v9 worth the upgrade from v8? or from norton av 2003 or 2004?

I believe so. Here are the specs:

Comprehensive virus protection for enterprise workstations and
network servers


Symantec AntiVirus Corporate Edition provides scalable,
cross-platform virus protection for workstations and network servers
throughout the enterprise. Symantec System Center™ enables
centralized configuration, deployment, policy management, and
reporting*, and allows administrators to audit the network to
determine which nodes are vulnerable to virus attacks. Administrators
can manage client and server groups logically, and can create,
deploy, and lock down security policies and settings to keep systems
up-to-date and properly configured.

NAVEX™ and Digital Immune System™ technologies provide virus
detection, analysis, and repairs via automated submission and
response mechanisms. Expanded Threat Detection and Threat
Categorization features detect unwanted spyware and adware, while a
Threat Tracer feature helps administrators determine the source of
blended threats spread through open file shares. Advanced behavior
blocking prevents client systems from being used for malicious
outbound activities, such as sending worms via email. A new Microsoft
Installer results in self-healing capabilities and a 50% reduction in
installation footprint. LiveUpdate™ technology allows administrators
to configure automatic updates for virus definitions, including
updates for definitions that are outdated.

Symantec VPN Sentry technology allows the administrator to ensure
that mobile and remote systems connecting to corporate resources via
VPN are compliant with security policies. The solution also ensures
that machines not connected to the network can store and forward
event data to administrators after reconnecting to the network.
