Over the years, computer viruses have evolved a great deal. Back in the 60’s, some programmers developed a game that can replicate every time it as run. It can even drain another computer’s memory. This game was called the Core Wars. To remedy what this game can do, those who created this game developed an application that could destroy copies replicated by the Core Wars. The application was named Reeper and came to be known as the first virus in the history. Also in that decade, the MS-DOS is fast becoming the top operating system worldwide. But young as it is, the the system was not developed as it is known today, that is so it was an easy target for virus then. That started the births of different viruses.
