Types of computer viruses and how they affect your computer - introduction computer virus is a program or codes that loaded onto your computer without your knowledge and run against your wishes and can copy itself in thes research i will talk about computer virus and the differents types of computer virus and how it infects the computer. This report on computer viruses is based upon a thesis written for the master of science degree in computer science from the university of tennessee in december 1989 by david r brown this thesis is entitled an analysis of computer virus construction, proliferation, and control and is available. There are a couple of different types of computer viruses: boot sector viruses, parasitic viruses, multi-partite viruses, companion viruses, link viruses and macro viruses these classifications take into account the different ways in which the virus can infect different parts of a system. Introduction to computer forensics computer forensics is the practice of collecting, analysing and reporting on digital data in a way that is legally admissible it can be used in the detection and prevention of crime and in any dispute where evidence is stored digitally. A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes viruses can also replicate themselves all computer viruses are man-made a virus can be easy to produce a simple virus that can make a copy of itself over and over again is relatively easy to produceeven such a simple virus is dangerous because it will.

Any computer connected to the internet faces a daunting range of electronic threats perhaps the biggest single threat to any computer is the humble software bug seemingly innocuous programming. A computer virus is a program that spreads by first infecting files or the system areas of a computer or network router's hard drive and then making copies of itself some viruses are harmless, others may damage data files, and some may destroy files. A computer virus is a type of malicious software that, when executed, replicates itself by modifying other computer programs and inserting its own code when this replication succeeds, the affected areas are then said to be infected with a computer virus virus. The very first computer virus to have been written and released was known as the creepy virus it was detected on arpanet, which was the forerunner for today’s internet basically, the virus was a self-replicating program created by bob thomas in 1971 three categories. Computer virus is a man made destructive computer program or code that is generally loaded onto a computer system without the knowledge of a user and causes unauthorized and unwanted changes to the information stored on the computer.
Introduction to computer viruses according to vermaat (2015, p 23), “malware, short for malicious software, is software that acts without a user’s knowledge and deliberately alters the computer’s and mobile device’s operations” malware includes many different things computer virus removal.

The computer virus is a problem to computer users at all levels including students, home users, corporate users, system administrators, corporate managers and even the anti-virus manufacturers the viruses are written by people with malefic intentions to trouble the innocent users. While some pranksters created virus-like programs for large computer systems, it was really the introduction of the personal computer that brought computer viruses to the public's attention a doctoral student named fred cohen was the first to describe self-replicating programs designed to modify computers as viruses. Introduction to computer security rev sept 2015 2 what is computer security 3 make sure your computer, devices and applications (apps) are current and up to date make sure your computer is protected with up-to-date anti-virus and anti-spyware software don’t click on unknown or unsolicited links or attachments, and don’t download.

Computers and viruses 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. A computer virus is a computer program that can replicate itself and infect a computer the term “computer virus” is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have this reproductive ability.
Computer viruses have come a long way from the early days of personal computers, when teenage hackers competed for bragging rights, creating malware designed for mischief or random mayhem. Introduction viruses, worms, trojans, and bots are all part of a class of software called malware malware or malicious code (malcode) is short for malicious software a computer virus is a type of malware that propagates by inserting a copy of itself into and becoming part of another program it spreads from one computer to another.
A virus is a biological agent that reproduces inside the cells of living hostswhen infected by a virus, a host cell is forced to produce thousands of identical copies of the original virus at an extraordinary rate unlike most living things, viruses do not have cells that divide new viruses are assembled in the infected host cell. A computer virus might corrupt or delete data on your computer, use your email program to spread itself to other computers, or even erase everything on your hard disk computer viruses are often spread by attachments in email messages or instant messaging messages. Computer operations like use of email system, stored information on the hard disk, accessibility to other resources on the desktop can get difficult or corrupted after a virus attack as the program renders some or the other functionality in your computer useless.
