Virus creators, or “virus writers”, started off writing viruses in the early 1980’s. Till the late 1990’s most of the viruses were just pranks made in order to irritate the computer users and to obverse how far a virus could spread. The writers were mainly young programmers, some still in their teens, who didn’t always understand the huge consequences of their actions. In the late 1990’s and early 2000’s, virus writers and hackers began to become aware of their talents, and started putting their talent to more professional and sometimes criminal use.
