- 1: Computer Viruses: Past, Present And Future
- Computer Viruses: Past, Present And Future In our health-conscious society, viruses of any type are an enemy. Computer viruses are especially pernicious. They can and do strike any unprotected computer system, with results that range from merely annoying to the disastrous, time-consuming and expensive loss of software and data. And with corporations ...
- 2: The Bulgarian and Soviet Virus Factories
- ... of Sciences, Sofia, Bulgaria 0) Abstract =========== It is now well known that Bulgaria is leader in computer virus production and the USSR is following closely. This paper tries to answer the main questions: Who makes viruses there, What viruses are made, and Why this is done. It also underlines the impact of this process on the West, as well as on the national software industry. 1) How the story began ====================== Just three years ago there were no computer viruses in Bulgaria. After all, these were things that can happen only in the capitalist countries. They were first mentioned in the April issue of the Bulgarian computer magazine "Komputar za vas" ("Computer for you") [ ...

- ... erased, and tried to reside on an opponent's system. In 1983 American electrical engineer Fred Cohen, at the time a graduate student, coined the term virus to describe a self-replicating computer program. Computer viruses are a sign of vandalism on computer systems or in cyberspace. They are self-replicating computer programs that disrupt the computers normal operation by means of interfering with its hardware and operating system. Viruses are designed to replicate and to avoid detection. In recent years computer viruses have caused a great deal of damage to personal computers and computer systems around the world. The damage can be extensive; mostly due to the loss of time spent recovering the infected data. A ...
- 4: Are "Good" Computer Viruses Still a Bad Idea?
- Are "Good" Computer Viruses Still a Bad Idea? Research Associate Virus Test Center University of Hamburg Vogt-Koelln-Str. 30, 22527 Hamburg, Germany bontchev@fbihh.informatik.uni-hamburg.de [Editor's note: Vesselin's current email address is bontchev@complex.is] During the past six years, computer viruses have caused unaccountable amount of damage - mostly due to loss of time and resources. For most users, the term "computer virus" is a synonym of the worst nightmares that can happen on their system. Yet ... keep insisting that it is possible to use the replication mechanism of the viral programs for some useful and beneficial purposes. This paper is an attempt to summarize why exactly the general public appreciates computer viruses as something inherently bad. It is also considering several of the proposed models of "beneficial" viruses and points out the problems in them. A set of conditions is listed, which every virus that claims ...
- 5: Polymorphic & Cloning Computer Viruses
- Polymorphic & Cloning Computer Viruses The generation of today is growing up in a fast-growing, high-tech world which allows us to do the impossibilities of yesterday. With the help of modern telecommunications and the rapid growth of the ... information with people from all sides of the globe. However, this vast amount of information transport has opened the doors for the computer "virus" of the future to flourish. As time passes on, so-called "viruses" are becoming more and more adaptive and dangerous. No longer are viruses merely a rarity among computer users and no longer are they mere nuisances. Since many people depend on the data in their computer every day to make a living, the risk of catastrophe has ...
- 6: Computer Viruses
- Computer Viruses Introduction In the past decade, computer and networking technology has seen enormous growth. This growth however, has not come without a price. With the advent of the "Information Highway", as its coined, a new ... extensions of people. An attack on a computers vulnerabilities are really an attack on peoples vulnerabilities. Today, computer systems are under attack from a multitude of sources. These range from malicious code, such as viruses and worms, to human threats, such as hackers and phone "phreaks." These attacks target different characteristics of a system. This leads to the possibility that a particular system is more susceptible to certain kinds of attacks. Malicious code, such as viruses and worms, attack a system in one of two ways, either internally or externally. Traditionally, the virus has been an internal threat (an attack from within the company), while the worm, to a large ...
- 7: Viruses
- ... computers are involved. A virus is composed of instructions hidden inside a program. These instructions copy themselves to other programs, and the cycle continues spreading. Fortunately, help is available; antivirus software is available to anyone. "Viruses first appeared in 1985. Then, they were largely created in university laboratories by mostly wayward geniuses keen to pit their programming skills against each other. Since then, errant programmers began to create newer and more destructive viruses targeted at specific user groups." (Yang, 1998) A computer virus can be as "evil as it sounds, snaking its way into personal computers, posing an occasional annoyance or a serious threat to all data." (Miastkowski, 1998) Symptoms can range from unpleasant to fatal. Computer viruses spread from program to program and computer to computer, "much as biological viruses spread within individual...members of a society." (Chess, 1997) Diskettes were the "primary carriers of viruses in the 1980s." ("Computer," 1997) ...
- 8: Computer Viruses
- Computer Viruses A virus is a program that copies itself without the knowledge of the computer user. Typically, a virus spreads from one computer to another by adding itself to an existing piece of executable code so ... if found, you shouldn't panic or be in a hurry, and you should work systematically. Don't rush! A Viruse may be classified by it's method of concealment (hiding). Some are called stealth viruses because of the way that they hide themselves, and some polymorphic because of the way they change themselves to avoid scanners from detecting them. The most common classification relates to the sort of executable code which the virus attaches itself to. These are: ¨ Partition Viruses ¨ Boot Viruses ¨ File Viruses ¨ Overwriting Viruses As well as replicating, a virus may carry a Damage routine. There is also a set of programs that are related to viruses by virtue of their intentions, ...
- 9: How the Government May Have Created AIDS
- ... opinions from many highly- respected physicians, like Dr. Robert Strecker, Dr. William Douglas, Dr. Cantwell, Dr. Hazeltine, Dr. Alonso, who all agree that the AIDS virus could never have occurred spontaneously in Nature. That animal viruses cannot jump species, as we are being told they did, as we are being asked to believe happened -- when allegedly, a green monkey bit an Africa and precipitated the pandemic of AIDS. We know as a scientific fact that viruses cannot jump species, unless they are specifically engineered to do so. And we also know for a scientific fact that the AIDS virus bears no resemblance whatsoever to any virus ever found in a green ... the interesting thing is, it is not a homosexual disease. It IS a man-made, mutated disease. It had to have been man-made. Sheep do not get together and do chemical experiments on their viruses. So, a man had to graft this bovine virus, which they know that's what it is, onto a human cell. It had to be made. So we know its man-made. They know ...
- 10: Viruses: Complex Molecules or Simple Life Forms?
- Viruses: Complex Molecules or Simple Life Forms? Viruses have been defined as "entities whose genomes are elements of nucleic acid that replicate inside living cells using the cellular synthetic machinery, and cause the synthesis of specialised elements that can transfer the genome to other cells." They are stationaryand are unable to grow. Because of all these factors, it is debatable whether viruses are the most complex of molecules or the simplest life forms. While the definition of living organisms must be adapted, the majority of evidence leads to the classification of viruses as living organisms. Viruses ...
