That's Conversational Monitor System (formerly Cambridge Monitor System),
and it is independent of, not "for", MVS.  To my knowledge, ALL viruses
on this system require some human action (to pull files in from the
"virtual reader" user input queue).  Although certain idiotic viruses
(the CHRISTMA virus being the most notable) have affected CMS, it is
not as subject to damage as is unix, where files are transmitted
directly to the user's file space, rather than an independent queue.
