had secretly hidden their warriors. During the night, the warriors emerged from
the wooden horse and overran the city. In computers a Trojan may refer to a

picture or audio or video file that would attract a user and would force him to
open it. Surprisingly hidden inside is usually something harmful, probably a
worm or a virus. These cut programs or images typically arrive through e-mail,

risks, you should never download files from unknown sites and people, or click

on computers because they are made with an intriguing mathematical
technological structure and complexity. An Internet worm can be contained in
any kind of virus, program or script. Usually they spread through e-mail or IM
messages any form of attachment or link in an email may contain a link to an
infected website. In first case activation starts when a user clicks on the
attachment while in the second case the activation starts when clicking the
link in the email. The most dangerous are internet Worms which will scan all available network
resources, try to connect to those systems and gain full access to them.
Sometimes inventor will release it into the wild in a single copy, and it will
be able to mutate, replacing its own code by itself.
