[G4] Who or What is "clama"

[Richard M. Kriss]

When I use the Log Out command under the blue Apple, I see there is user
call clamav.  I have no idea what this is about. I went the OSX 10.4 (Tiger)
Preferences/Accounts and there is NO account for clamav.  I used the
spotlignt and found some stuff in an X11 with name clamav.  I trashed it and
still can't ditch the 'clamav' user. I do not recall ever seeing this until
I upgraded to 10.4. Anyone else  have a clamav lurking around?
