If it is not hooked up to the internet there is really no critical reason to have anit-virus on it. If you are worried about a virus from a disk, just run a scan on the disk in the other pc first.
The important thing is: What anti-virus program are you running?

For example in the free AVG Anti-Virus program, they have update files available for manual download on their website.
