Malware, viruses, worms, Trojan horses and spyware
Malware a portmanteau for malicious software is any software intentionally designed to cause damage to a computer , server , client , or computer network   by contrast, software that causes unintentional harm due to some deficiency is typically described as a software bug. Programs are also considered malware if they secretly act against the interests of the computer user. For example, at one point Sony music Compact discs silently installed a rootkit on purchasers' computers with the intention of preventing illicit copying, but which also reported on users' listening habits, and unintentionally created extra security vulnerabilities. A range of antivirus software , firewalls and other strategies are used to help protect against the introduction of malware, to help detect it if it is already present, and to recover from malware-associated malicious activity and attacks. Many early infectious programs, including the first Internet Worm , were written as experiments or pranks. Malware is sometimes used broadly against government or corporate websites to gather guarded information,  or to disrupt their operation in general. However, malware can be used against individuals to gain information such as personal identification numbers or details, bank or credit card numbers, and passwords.
An introduction to computer viruses: problems and solutions
Virus : Virus is a computer program or software that connect itself to another software or computer program to harm computer system. When the computer program runs attached with virus it perform some action such as deleting a file from the computer system. Worms : Worms is also a computer program like virus but it does not modify the program. It replicate itself more and more to cause slow down the computer system. Worms can be controlled by remote.
The purpose of this paper is to discuss various types of computer viruses, along with their characteristics, working, effects on the computer systems and to suggest measures for detecting the virus infection in a computer system and to elaborate means of prevention. The author undertook an extensive study and review of the literature available online and on relevant web sites on the present topic. A large number of viruses were found during the study, which are causing serious damages to computer systems. The author suggests ways to detect and prevent the different computer viruses. The research is based on and limited to the study of the relevant literature available on different relevant web sites. The research will benefit business organizations, business houses, educational institutions and libraries working in fully computerized environments, in detection of viruses and preventing infection of their computer systems. The society will also benefit by attaining knowledge about the different types of computer viruses and the measures of prevention of infection.

According to Webster's Collegiate Dictionary , a computer virus is "a computer program usually hidden within another seemingly innocuous program that produces copies of itself and inserts them into other programs or files, and that usually performs a malicious action such as destroying data ".
