First you need to have Client Server Anti virus program like
Trend Micro Office Client

Next
Update your Ghost image after installing the Antivirus Program and updating your Windows firewall settings.
Then re-ghost every machine, using multi-cast.

by this you will come up with a clean solution.
or else you will endup with a traces of virus which will spread again.(these days the Viruses are more intelligent

If you have windows XP SP2, then you better stick with XP2.
Norton Firewall is not stable to my experiance.
Just install the Norton Antivirus.

you better install the AntiVirus Client Server software, by this you will have a central control on your network and good monotering and reporting system

I can suggest, Trend Micro Office Scan 7.

Hi,

YEs if you install the norton antivirus corporate edition and every day update the definition of viruses then your network will  99% virus free.

In the Antivirus software case

1. Update every day the virus definition its required
2. make sehedule of update virus in the window secdhule task so virus definition automatic install


Use a better firewall like zone alarm its user friendly and better so its also prevnet the use less traffic

What is the product name for Norton and its version.

I am not sure but to my knowledge
Norton 2005 is not an Corporate product, its an end user product....
i dont think you will achieve client server architecture with Norton 2005...
