Be
aware that the people who create viruses can use known hoaxes to their
advantage. A good example is the AOL4FREE hoax. This began as a hoax
warning about a nonexistent virus. Once it was known that this was a hoax,
somebody began to distribute a destructive trojan horse (a trojan horse
differs from a virus in that it does not reproduce itself) in a file named
AOL4FREE, attached to the original hoax virus warning!
