Types Of Malware And How They Attack

by Jake M. Black on November 12, 2009

Malware refers to harmful software or scripts that are affect computers. Malware such as Trojan horses and viruses will be described.

The word malware is a shortened phrase for “malicious software”. Generally, malware are programs that cause damage to computer networks, storage systems, servers and computers.

Viruses are the most common forms of malware. They are usually made of scripts or programs that multiply and spread files within a computer, server or network. They also spread files from one computer to the other. This is usually done without permission of the user. Some people define viruses as programs that trick the user or computer to install them for the purpose of corrupting deleting, or dislocating the data stored in the hard drive. This is a wrong definition. A win32 virus may not damage the data, but it is distinguished by its ability to multiply within a computer or the user does server. Mostly, the damage is done when a user attempts to eliminate the virus. Viruses are spread through downloads or e-mail attachment. They can also be spread from one computer to another through portable storage devices, like a flash drive or memory stick.

Users should also note the definition of a “worm”. A worm is a type of virus that spreads in a network of computers by replicating copies of itself in each of the computers in the network.

How can you destroy a computer virus? There is a lot of software that can be used to detect and destroy viruses. Anti-virus software works by scanning and destroying all the malicious scripts in the computer. Software with similar behaviour to virus scripts will also be destroyed. You should protect your computer from viruses by installing virus protection software. You must also desist from downloading executable files. Executable files are delivered through e-mail attachments or internet downloads. Downloading executable files from unknown sources is risky. E-mail programs like Gmail and yahoo can scan files for viruses.

Another type of malware is a “Trojan horse”. A Trojan horse is a stealth program that tries to enter the computer without the user’s permission or knowledge. The word Trojan horse is derived from a Greek myth about characters that pass through security walls by presenting or hiding themselves in a different form. One example of a Trojan horse is the ‘swen virus’ that presented itself as a Microsoft application.

A Trojan horse is a lethal form of malware. The consequences wrought by a Trojan horse infection include loss of data, corruption of data, alteration of data, movement of data and hacking. A Trojan horse can phish passwords, credit card numbers and other sensitive information. Viruses disrupt our computers, and they should be swiftly done away with.
