Do any have the execute bit?  Ususally you find binaries in /bin, /usr/bin,
/sbin, /usr/sbin.  Check there for clam and find one with the execute bit
(find / -type f -name \*clam\* -perm +700).  The sacred handwavings to 
invoke the finer majik of the find command are left as an exercise to 
the reader.

But it's not (1/MegaHard), so: Robert will be your mother's brother!

See above.

There are nasties for Linux; just a lot less than for Windows.  You 
need to really try out chkrootkit and things like that.  A virus on 
Linux will only clean out a user's files rather than destroying 
the system usually (unless you run as root).

If you host files or mail for Windows users then a virus scanner is a 
good investment on your Linux machine.
