Just about any modern A/V software should allow "off-line" updates.
Symantec for instance provides "Intelligent Update" downloads. You go to
the website from an internet connected PC and download the Intelligent
update, then use it to update your non connected systems, or update a server
and push the definitions to connected LAN clients.

Maybe wasn't my question clear enough, All the security problems
related to people trying to ad a laptop to the network or trying to
connect to the Internet from the work computers have been resolved.
As I tried to explain in my first e-mail, The point is how to update
an anti virus with out allowing him to connect to the Internet, and
witch anti virus would be able to do this ( threw diskette for
example).
