Do you know that the concept of computer viruses comes from a game

The origins of computer viruses

The concept of computer viruses actually originated quite early, and in the years before the first commercial computer appeared, the pioneer of computer Neumann (John Von Neumann) in one of his papers, "The theory and understanding of complex automata", has outlined the blueprint for viral programs. At the time, however, the vast majority of computer experts were unable to imagine the process of reproducing themselves.

In 1975, the American science writer John Broullers John Brunner wrote a book titled "The Shock Knight" (Shock Wave Rider), which for the first time described the story of computers as a tool for the struggle between justice and evil in the information society, Become one of the best bestsellers of the year.

In the summer of 1977, Thomas Ches Ryan (Thomas.j.ryan) 's science fiction "P-1 Spring" (The Adolescence of P-1) became the best-selling book in the United States, where the authors described a virus that could infect each other in computers, and the virus finally controlled 7,000 computers, causing a disaster. Things in the virtual science fiction world have finally become a nightmare for computer users in a few years.

And almost at the same time, the famous At&t Bell laboratory in the United States, three young people in the work, very boring play a game: each other to write a program to eat others to fight each other. This game, called "Core war", further reflects the concept of "infectious" computer viruses.

On the November 3, 1983, Fred Cohen, a University of Southern California student, wrote a program that would cause the system to crash under the UNIX system, but the program did not attract the attention and Frede Cohn of some professors. Cohen's publication of these procedures in order to prove his theory was a shock at the time. Cohen's program, let computer viruses have a destructive concept of concrete shaping.

However, this process of infection and destruction is really called "virus", in two years later in a "Scientific American" monthly. A columnist called Dutney (A.k.dewdney) is talking about the "core wars" and the Apple two computer (don't doubt that it was the Apple two type computer that was popular at the time, when our familiar PC was still out of sight), and began to call this program a virus. From then on, we have a "virus" name for the infected or destructive program.

The first real computer virus

By the year 1987, the first computer virus C-brain was finally born (which seems not to be a celebration). In general, the industry is generally recognized as a truly complete feature of the computer virus ancestor. The virus program was written by a pair of Pakistani brothers: Baxter (Basit) and Amtet (Amjad), who run a local shop selling personal computers, and because of the prevalence of local piracy, their purpose is mainly to prevent their software from being arbitrarily stolen. As long as someone steals their software, C-brain will attack and eat the remaining space of the Pirate's hard drive.

The virus did not have much lethality at the time, but later some people with C-brain as a blueprint for the production of some variants of the virus. and other new virus creations, have also come out, not only personal creation, even a lot of creative groups (such as NUKE,PHALCON/SKISM,VDV). All kinds of anti-drug, anti-virus and anti-virus software and professional firms have emerged. For a time, a variety of virus creation and anti-virus program, constantly introduce new, as the hundred schools of contention.

The famous virus of the DOS era

The so-called "Dos era virus" means that this is from the DOS era of the old, you readers can not think that you have now entered the age of Windows 95/98, will not infect the DOS period of the virus. In fact, because Windows 95/98 is at best a set of operating systems on DOS, so even under Windows 95/98, accidentally will be irritated!

Jerusalem (JERUSALEM)

This antique-grade virus actually has a more widely known nickname, "Black Friday." Why is there such an interesting nickname? The reason is simple: because as long as the number 13th is Friday days, the virus will attack. And the attack will terminate all users of the program executed, the symptoms are very vicious.

Michelangelo (Michelangelo)

Michelangelo's name, for some early computer users, is really a well-known, thunderclap piercing. The famous reason, in addition to its own generation of art master Michelangelo's name, more importantly, it is amazing: every year to the March 6 Michelangelo's birthday (which is why it is called "Michelangelo"), the virus will be the format of the hard drive to the master birthday. So, all the information you have worked hard to build is destroyed, never to turn over the day.

Monkey (Monkey)

Monkey is said to be the first "boot" of the virus, as long as you use the monkey infected with the system floppy disk boot, the virus will invade your computer, and then the next step to remove the hard disk partition table, so that you turn on the "Invalid Drive Specification" information. Monkey is more difficult than a "file-type" virus that can only be poisoned by executing infected files.

Music bug virus (musical bugs)

This attack will sing loudly, and even cause data loss, no boot of the virus, it is Taiwan's indigenous virus. So, when you hear the sound of music coming from your computer, don't think your computer is smarter than others, it's probably poisoned.

In fact, this can sing a lot of viruses, there is another famous virus (name forgotten) when the attack will also sing "Two Tigers" it!

DOS-era viruses are quite complex, and people are constantly rewriting existing viruses. At the end of the period even someone wrote the so-called "dual-body engine", can create a more diversified appearance of a virus, people are impossible to guard against! But the symptom of the virus attack is all kinds, some can sing, some will delete the file, some will format the hard disk, some will also show all kinds of graphics and sound effects on the screen. Fortunately, these DOS-era antique-level viruses, because most of the anti-virus software can be easily cleaned, so the lethality has been worse than before.

The advent of Windows time

With the global popularity of Windows 3.1, the PC operating environment has been officially proclaimed into the Windows age. In the immediate aftermath, Windows 95/98 was a big seller, making the operating environment of almost all PCs now in Windows state. And in the Windows environment most well-known, probably belong to "macro virus" and "32-bit virus".
