Windows viruses hitting linux.....

[Joel Hammer]

I guess my question is: What commands are issued by the viruses to do their
damage (erasing files)? 
Is is possible with samba to disallow certain types of commands, say
commands with  wildcards that erase files? Or, in a more general sense,
could samba limit what clients can do in terms of copying and writing files
in such a way that viruses couldn't do much harm but users wouldn't be
inconvenienced?
