computers.
Most people, from the corporate level power programmer down to the

4. Spontaneous Generation: this last vector is at the same time
the least thought of and the least likely. However, because
virus programs tend to be small, the possibility exists that
the code necessary for a self-replicating program could be
randomly generated and executed in the normal operation of
any computer system.

Even disregarding the fourth infection vector, it can be seen that the
