Why would you need such a thing?  Are you reading email and browsing  
the web from you cluster nodes?  Do you have users downloading the  
latest e-birthday card or nifty *free* game on the nodes.  I think  
not.  They're sitting behind a head node or similar.

I wouldn't put AV software of any kind on the nodes.  heck, if you  
have a problem, you'd just wipe and reinstall from known good media.

This is no different than big corporations with Windows desktops..  
they're locked down from external media, and boot from a shared image  
on a server and have no outside internet access.

If you're running quasi-real time software (e.g. Labview) doing  
instrument controls?

It's perfectly reasonable to run Windows machines without virus  
checkers, etc., if you have a fairly decent software configuration  
management process in place.

Relatively few clusters fit in that category.
