The Evolution of the Computer Virus
Introduction
In simple terms a virus can be defined as software, which is unwanted and executes arbitrary code on systems. It acts as a small software program, which has the capability of exploiting other software programs in order to piggyback[1]. The terms viruses and malwares are used interchangeably, however, in technical terms, the viruses are a subset of malware and so are trojans, worms and rootkits.
The name for the “Computer Virus” has actually derived from its biological counterpart because of their proximity in properties. Similar to the functioning of biological viruses, a computer virus must use another program to exploit some other program in order to start functioning. Hence, this

‘The root of virus evolution can be drawn back to 1949 when the scientist John von Neumann introduced the concept of self-replicating programs. The design suggested by Von Neumann for the self-producing programs is said to be the first computer virus.
The predecessors of the current form of viruses date back to the 60s.It was then that a game called “Core Wars” was developed which had the capability of regenerating every time it was run. This game could also the exhaust the memory of the computer of other players. Similarly, another application named Reeper was developed by the founders of “Core wars”, which could delete the copies made as a result of running of “Core Wars”. This turned out to be one of the first antivirus applications.
During the same time, another malicious code named “Brain” was created in 1966, which made the contents of the disks inaccessible by infecting the boot sectors of disks. The main target of this malicious program was MS-DOS which itself was relatively new at that time. The same year, another application named “PC-Write” was developed which served as the first Trojan.
During the development phase of viruses it was soon realized that infecting the files could increase the damages caused to the computer systems. Hence, 1987 saw the appearance of “Suriv02”, a virus infecting COM files and leading to development of other viruses, like "Viernes 13"
The article first addresses the issue of whether or not to consider viruses as living. Although viruses used to be thought of as being biological chemicals due to the fact that they consist of nucleic acids
The first known ransomware was written by Joseph Popp in 1989 and was known as PC Cyborg or “AIDS.” This
It is often argued whether viruses are living or not. Those who don’t believe that viruses are living generally base their opinion off of the fact that they do not follow the basic definition of “life”. They do not carry out life-sustaining functions on their own like normal organisms. On the other side of the argument, some believe that viruses are in fact, living beings, which is where I rest my opinion.
Viruses, Plagues, and History, written by Michael Oldstone, is an insightful and highly educational book that details the history of, that’s right, viruses and plagues. Through typically dry, yet engaging prose, Oldstone recounts what seems like all of it while simultaneously bringing to light the contributions of those brave scientists who asked themselves, “why.” He focuses his attention on some of the most notable viruses such as smallpox, yellow fever, measles, polio, and later he focuses on more contemporary battles against disease.
A Virus is a piece of malicious code that has the intent to damage your system.
As we know virus protection software is a code written by one of the programing languages that we know. This code works as a search engine looking for infected files in the entire system or specific locations on the system. The idea depends on two important factors which are, search engine and viruses’ data base. The following scenario explains how people get viruses and how virus protection software works.
Computer virus is a program that can copy itself and infect a computer without the permission or knowledge of the user. Viruses perform some type of harmful activity such as accessing private information or corrupting
I recently read an article written in The NEWYORKER called The Deadliest Virus by Michael Specter. The article talked about the Avian Flu virus, also known as “bird flu”. In the article, Specter interviewed many people, but the most important person, in my opinion, is a virologist who conducted research on the Avian Flu, Ron Fouchier. This article raised many ethical questions. The questions are as followed: Should research be conducted on this virus? Does Fouchier’s research pose a threat? Does the risk of the work outweigh the benefits of the research?
Viruses and worms are malicious programs that self-replicate on computers or through computer systems without the user being cognizant. Worms are a series programs that repeat themselves from system to system minus the use of a host fie. Worms use methods to infiltrate remote computers and launch replicas of themselves like email messages or coping files to an accessible disk. A computer virus is a
The Creeper is considered to be one of the first and least dangerous virus created. It was basically an experiment program written by Bob Thomas, in which he choose to display a message, "I'M A CREEPER: CATCH ME IF YOU CAN", without creating serious damage to the device [11]. This virus infected computers running the TENEX operating system. A year later Ray Tomlinson came up with an ideas to delete the Creeper Program, thus creating the Reaper, a computer worm. The Reaper was succesful and eventually stopped the spread of the
Two of the common known attacks on computing systems are the deployment of computer viruses and malware.
PREVIEW: First, I will give you information about the virus itself. Secondly, I will talk about why
To understand the business of malware, one must understand how malware has evolved in the past twenty-five years. Malware, which includes all kinds of malicious software, was originally created to show the weaknesses of computers. The first type of malware, created in 1986, was a virus called “Brain.A. Brain.A was developed in Pakistan, by two brothers - Basit and Amjad. They wanted to prove that PC is not secure platform, so they created virus that was replicating using floppy disks” (Milošević). Even today malware is still used to check the security of machines.
Many types of computer virus has been spreading in computers since 1960. The first a computer virus discovered in 1970 and called The Creeper virus on Arpanet browser (anon, 2013)
