Virus scanner - From Lin to Win!

Hey everyone, I am needing a virus scanner for Dos/Windows based viruses than can run on linux over an SMB reference [\\hazel\c$] or via a mount point [using the -t smbfs of mount.] What would you recommend? Which packages? I'm not afraid to build from source, so just so long as there is a compatible .tar.[gz bz2] that is fine =o) Thanks =o) Jon Jeffels
