If you have internet access, get you a copy of 40Hex...

A virus doesn't need to do anything of the above to be a virus (ie reproduce).
It hasn't to be self-modifying, it doesn't have to use port writes, can
infect non-running EXE (or DLLs), doesn't need low-level access to an
active partition.

Strictly speaking, I am disadvantaged here because you can post source code
to prove your point. If I don't I could be called a liar and if I do, i'll
be called a criminal or a vandal !

So, since you and Peter Fitzsimmons seem to be reasonnable persons, let's
say that I'll send you more info through crash mail.
