Virus - uses the host's "cells" to reproduce and re-infect others
(Virus places its own code inside existing executables on the infected
host)

Worm - travels from system to system, like the parasitic worms dogs (and
some people) get.  Worms don't modify existing executables, but they do
make copies of themselves on the infected hosts.

Some malware could be said to be both worm-like and virus-like.
(most viri have worm-like features, but not all worms have viri-like
features)

Trojan - any program described to be benign or beneficial but actually
a worm or virus in disguise.  See "Trojan Wars".
