Thank you.
The venom spitting "malicious rumour-mongerers" are easily recognized
and they never contribute anything valuable to society, and they must
be
ignored. However, we all are afraid of the handy-work of another type
of
malicious people, the destructive Windows critter-makers who are
generally
not (low-level Assembly, FORTRAN or C) computer programmers.

You don’t understand. A Windows program cannot be run in DOS
(or Linux),
while DOS can be run by Windows. Theoretically, any ANSI C or FORTRAN
code can be compiled for any operating systems and/or different CPU
types. Assembly, on the other hand, is bound to particular hardware
types like
Intel x86/7 (PC) or Motorola 68x (Mac), but it can interface smoothly
with
any computer language.
To transfer a whole Windows program within a DOS program to Windows is
possible, of course, but it will make the DOS program very large.
This would
also be a most inefficient way to spread viruses through Windows.

Having a domain name, I'm being bombarded daily by both spam and
viruses.
News groups are also being attacked. Usually, you are enticed to open
some e-mail and run an attached batch or script file, or extract and
run
an executable from a zip file.

In the same time frame, I was also attacked by an e-mail virus. It
infected
a few major applications by attaching itself to them. I had no choice
but
to re-install Windows and all the applications.
It is criminal to knowingly damage the property of others. Hence,
virus
writers will not publicize their (real e-mail) address. Do not
execute files
the source of which you don't know.
By the way, have you run my program? What would you do differently?
