Our Sophos firewall found a botnet on our OES servers running with NSS volumes.
At the moment we have no antivirus on the OES servers. I never tought linux was so vurable for virusses and certainly not on Novell :).

We use McAfee for our workstations which has a Linux scanner.
Sophos for our firewall so we can also use it as Linux scanner.

What is the best to use and what is your experience?

Do you have to exclude certain partitions of the NSS filesystem? Is this for McAfee and for Sophos or is this something from the past?
