Virus Trojan Worm

1. A computer worm is a standalone malware computer
program that replicates itself in order to spread to other
computers. Often, it uses a computer network to spread
itself, relying on security failures on the target computer
to access it. Unlike a computer virus, it does not need to
attach itself to an existing program. Worms almost always
cause at least some harm to the network, even if only by
consuming bandwidth, whereas viruses almost always
corrupt or modify files on a targeted computer. It's Kind of
like a virus, but not exactly.

2. • Each day, worms are becoming a more common
occurrence on the Internet. As the incidents
increase, we must be thinking proactively in order to
lessen the negative effects these worms have on the
Internet community. It is important to remember that
the livelihood of many businesses is based on an
Internet presence. The monetary losses incurred by
businesses relating to these worms are hard to
measure. Some estimate losses for each
occurrence to be around $1 billion. 1 The true value
of damages may never be known.

3. • Viruses can occur in games of all sort,
people can find you username and
search you on Google> or if you have
an instagram!!!!!! if your following
them, they can search you on Google
and find out where you live, so don't
put your location!!

4. • A computer virus is a computer program that
can replicate itself and spread from one
computer to another. The term "virus" is also
commonly, but erroneously, used to refer to
other types of malware, including but not
limited to adware and spyware programs that
do not have a reproductive ability. Malware
includes computer viruses, computer worms,
Trojan horses, most rootkits, spyware,
dishonest adware and other malicious or
unwanted software, including true viruses.

5. • Viruses can cause computer "break downs"
which can turn off your computer completely,
this can be caused by people or random links
that cause viruses! People can hack your
computer when your logged on to FaceBook,
Twitter etc.. and hack your account so they
can your pictures if you keep it private, some
people can stalk you until you leave so they
can get to the computer and cause a virus so
they "own" your computer!

6. • Your system will suddenly
slow down.
• You will see activity on your
screen that you did not
cause.
• Data files become corrupted
or are missing.
• Unexpected changes to the
content of files.
• The program doesn’t run or
it functions incorrectly.
• Certain features aren’t
available anymore.

7. • A Trojan horse, or Trojan, is a malicious application
that masquerades as a legitimate file or helpful
program but whose real purpose is, for example, to
grant a hacker unauthorized access to a computer.
Trojans do not attempt to inject themselves into
other files like a computer virus. Trojan horses may
steal information, or harm their host computer
systems. Trojans may use drive-by-downloads or
install via online games or internet-driven
applications in order to reach target computers. The
term is derived from the Trojan Horse story in Greek
Mythology because Trojan horses employ a form of
“social engineering,” presenting themselves as
harmless, useful gifts, in order to persuade victims
to install them on their computers.
