VIRUS
PROTECTION
Viruses are programs designed to replicate and implant themselves
into files, programs, or your computers operating system.
They can have effects, from slowing your computer down to erasing
files, causing your system to permanently crash.
Types
 |
Trojan horses
A malicious program that is disguised as or embedded within
legitimate software. The term is derived from the classical
myth of the Trojan Horse. They may look useful or interesting
(or at the very least harmless) to an unsuspecting user,
but are actually harmful when executed. Often the term is
shortened to simply Trojan. |
 |
Worms
Uses a network to send copies of itself to other systems and it
may do so without any user intervention. Unlike a virus,
it does not need to attach itself to an existing program. Worms
always harm the network (if only by consuming bandwidth),
whereas viruses always infect or corrupt files on a targeted
computer. |
 |
True Viruses
A self-replicating computer program that spreads by inserting
copies of itself into other executable code or documents.
Common types of true viruses includes:
-
E-mail viruses - An
e-mail virus will use an e-mail message as a mode of
transport, and usually will copy itself by automatically
mailing itself to hundreds of people in the victim's address
book.
-
Logic Bombs - Logic
bombs maliciously cause legitimate applications to fail. "An
application, for example,
might delete itself from the disk after a couple of runs as
a copy protection scheme."
