Well, having in mind that I have participated the writing of both my
paper and the Virus-L FAQ, I obviously know what's written in them...

Yes, I know that, of course... I was just pointing out that the
"common" understanding of the term "virus" (by the end user) as
"something that messes with my files" is not always correct, even for
the currently existing types of viruses on the IBM PC. These viruses
(boot sector infectors, file system infectors, companion viruses) do
not match even Dr. Cohen's natural-language definition of the term
"virus", unless you define "program" and "attach" too broadly. And
IF you define them broadly enough, a "worm" will fit in the definition
of the term "virus" too. They are essentially one and the same thing,
from the mathematical point of view... Nevertheless, for reasons of
convenience, we prefer to differentiate between them in practice.
