     Now that's getting down right, uh, not-very-intelligent.
Anybody with enough knowledge to analyse an object code file
probably has sufficient tools to read sectors anyway.  For
the rest of us who have no intention of playing with their
object code they do us the great honour of create a situation
where virus distribution can increase.  All we need now is
somebody forging a copy of this 'only_ste' demo kit with a
virus in place of the original boot sector and dozens of
STE owners are going to find themselves doubting the wisdom
of their purchases.

     While we're on the topic of viruses, I was very impressed with
the "finish" of VKiller.  It got me to thinking about such programs.
VKiller identifies ST boot sectors and where possible specifically
identifies viruses.  But even the warning about boot sectors is
well done.  I was just thinking that many of us use Atari ST's in
"mixed environments" with MS-DOS machines and it would be helpful
if VKiller identified MS-DOS boot sectors as well.  I wouldn't go
so far as to try and keep up with the MS-DOS virus situation completely,
but just give a warning like this:

"MS-DOS Executable boot sector found.  If this disk was not supposed
to have one, you might want to discuss this with whomever supplied
the disk."

     That way you could alert an MS-DOS user that s/he might have
a virus.
