The FreeBSD server itself is immune to that virus.  I'd look at the 
files and ask how they got there (who put them there).

Second, personally I'd recommend you go into the ports tree and install 
ClamAV.  Then you can run Clamscan and that will flag which files are 
"infected".  Then you can go through and delete them or quarantine
