Hi Richard,
NetWare still has life left in it, but with the EOSL for SAV 10, Symantec will no longer have a supported product which is designed to scan and protect its file systems. There's no guarantee that SAV 10 defs will be available on July 5 or will function on SAV for Netware.
With regards to definitions, extensions, etc please see the following articles and thread:
