True, I hadn't thought of that.  Although it is also true, to some extent,
that the checksum must be stored somewhere...... Perhaps a virus could
simply change the checksum on a random basis, thereby giving false (?)
reports to the system people.  Then, when it's getting to the point where
it seems there's something wrong with the checksum software, the virus could
insert itself, which would be taken as another false report.  Problem with this scheme is finding the checksum byte(s)....
