Who & why are invented the virus for software?

Answer 1

The first computer virus to affect a general-purpose computer system, Pervade was created as a means of distributing the game "Animal" on UNIVAC systems. First released in 1975 by John Walker, who would eventually establish Autodesk, the virus spread through files transferred between systems on magnetic tapes.

Created by ninth-grader Rich Skrenta in 1982, Elk Cloner was the first computer virus to affect personal computers, namely the Apple II. The virus hitched a ride on the command used to list files. It would occasionally cause crashes, and on the 50th time an infected disk was used, it would display a poem.

University of New Haven professor Fred Cohen introduced the term "virus" to the lexicon of computers. He used the phrase in a 1984 research paper (Computer Viruses - Theory and Experiments) in which he described threats self-propagating programs pose and explored potential defenses against them.

Two Pakistani brothers, Amjad and Basit Farooq Alvi, created the first IBM personal computer virus in 1986 as a way, many virus historians believe, to advertise their company, Brain Computer Services. The brothers programmed the Brain virus to overwrite the boot instructions found at the start of system disks.

A program called "Elk Cloner" is credited with being the first computer virus to appear "in the wild" -- that is, outside the single computer or lab where it was created. Written in 1982 by Rich Skrenta, it attached itself to the Apple DOS 3.3 operating system and spread by floppy disk. This virus was originally a joke, created by the high school student and put onto a game. The game was set to play, but release the virus on the 50th time of starting the game. Only this time, instead of playing the game, it would change to a blank screen that read a poem about the virus named Elk Cloner. The computer would then be infected.

The first PC virus was a boot sector virus called (c)Brain, created in 1986 by two brothers, Basit and Amjad Farooq Alvi, operating out of Lahore, Pakistan. The brothers reportedly created the virus to deter pirated copies of software they had written. However, analysts have claimed that the Ashar virus, a variant of Brain, possibly predated it based on code within the virus.

Answer 4

its history is...(its the fact)..it was a pakistani software engg student in US who developed the 1st virus about 20 yrs back i guess,n the purpose was i think...it was his final or major project or thesis project,,that afterwards turned in a blinder...

Answer 5

I dunno much about their history, but they are usually developed by antivirus companies for the sale of their products. McAfee is believed to develop powerful viruses to disable systems having Norton, its rival in the antivirus world.
