on top of warhol worms there are also the plain ordinary trojans which
are now able to be spread far and wide enough by manual labour as to
become a significant enough problem for anti-virus products to change
their focus...

overwriters are viruses by cohen's formal *and* informal definitions...
if zvi wants to use his own definitions, he's free to do so but the
discussion won't go very far...

In 1984, the first experiments with `Computer Viruses' as we know them
today were performed. [1] To quote this paper:
``We define a computer `virus' as a program that can `infect'
other programs by modifying them to include a possibly evolved copy of
itself.''
These `Viruses' had many implications for integrity maintenance in
computer systems, and were shown to be quite dangerous, but their
potential for good was also introduced. A practical virus which reduced
disk usage in exchange for increased startup time was described, and
this technique that is now commonplace in personal computer systems. A
formal definition for viruses, which for mathematical reasons
encompasses all self-replicating programs and programs that evolve and
move through a system or network, was first published in 1985. [4] This
encompassed many of the worm programs under the formal umbrella of
computer viruses. This work also pointed out the close link between
computer viruses and other living systems, and even melded them into a
unified mathematical theory of `life' and its relationship to its
environment. These experiments were terminated rather forcefully because
they were so successful at demonstrating the inadequacy of contemporary
computer security techniques, that administrators came to fear the
implications.
