Antivirus protection without the Internet

We have some never-on-a-network PCs set up in a lab at work; all are running Windows Vista. We need a good way to keep up-to-date antivirus software on them without relying on an internet connection.

We can't connect our lab computers to the outside world without being required to install a lot of unwanted software, so we have elected to keep them off the internet entirely. All file transfers take place via USB drives or CDs. A few years ago, we had a student infect one of the computers with a virus they transferred from their USB drive. To remove it, we were able to install a copy of McAfee VirusScan Plus from CD, but McAfee now tells us that they no longer provide update CDs/DVDs and the only way to update and get new virus definitions is via an internet connection.
Students only rarely have access to these computers. We can forbid students from ever using USB drives in these computers, but this is inconvenient and mostly unenforceable.
What virus protection strategy should we be using, and why? How often should we update? If we get infected again, is there going to be any way we can remove the problem without connecting to the internet?
