I'll 2nd Jay's comments on nod32, been running for 2 years now on 8 machines, all virus free, small footprint (written entirely in assembly language), 1 server gets the signature updates other machines update from that. This feature is avaialble free when you buy a multi user license. Best part, it uses a User ID and password to access the signature servers, no wonky expiration mechanism installed on your machine that eats overhead. And no, I don't work for eset
