How do you guys protect Samba shares from Win32 based viruses?

[Kevin]

That's pretty much the question.  I've got Symantec
NAVCE running on my NT server protecting itself, the
Windows clients and the Exchange server, but what do i
do about my Linux based Samba server?

Will a linux based AV app search for Win32 based
viruses?

Thanks,
