After reading all of the other replies (including the ones that pointed 
out that the PCI DSS requirement had changed the terminology from 
"virus" to "malware"), why not claim you are meeting the requirement by 
doing something useful like running chkrootkit or rkhunter on a regular 
basis?  That way you would be scanning the systems for the only malware 
known to actually pose a threat to a Linux box.  It may be a low 
probability of infection (as others have pointed out) but should satisfy 
the auditor and hopefully will just be a low cost exercise in futility 
as long as reasonable security policies are followed.
