I really doubt there is a virus on their system; there just aren't any unix viri out there. I have only heard of a very few proof of concept unix viri. In all likelihood, you have a trojan or some other security problem. And that's how you should apprach this; as a security problem. If files are being modified on the system, someone has gained privlidges beyond what they ought to have. BTW, there is a virus checker from McAfee that runs native under FreeBSD, but it is meant for checking MS-DOS/Windoze files for viruses. A lot of people use unix file servers because NT servers suck. This make is eash to check all files on the server wihtout moving themover the network to a DOS box to check for viruses.
