History of Virus:
The first computer virus had been firstly detected on the early ‘70s. In 1971 there was a computer virus that was called Creeper virus and it was detected thru the Advanced Research Projects Agency Network or commonly known as ARPANET. Creeper was the fruit of experiment by Bob Thomas. This Creeper program has the capability to replicate itself. The main purpose of this virus was to inflict the Mainframe made by DEC in the late 1960s. This mainframe was called PDP-10 or Program Data Processor Model 10 that ran under TENEX operating system. The Creeper virus was famous with the line saying, “I’m the creeper, catch me if you can” for all those infected computers. Because of this first virus there was a first anti-virus that had been made and it was called the “Reaper” that has the capability to delete the Creeper virus.
“Rother J” was the first virus that had gone out over the networks.This virus had been written by Richard Skrenta. Apple DOS 3.3 was the operating system that had been victimized by this virus and the spread had been possible through its floppy disks. Out of amusement during Richard’s high school life it was injected into a game.
During the times before the popularity of computer networks the viruses can only be spread through the use of media files, portable storages like floppy drives, etc.
Nowadays, viruses can be spread through networks and they have the capability not just to take control of your program in your computer but to detect your activities and get some non-disclosure information about you.
A simple virus can be made by using the assembly language program and those virus generators have other ways by using other type of programs to give harm to others.
There are some rumors that allegedly they are accusing those anti-virus makers as one of those who make viruses to spread over the networks. As some bad business concept, they create problem in order to sell the solution!
