The history of computer crime dates back to 1971 and the first computer virus called Creeper, created by Bob H. Thomas, who was an engineer at BBN (Dalakov, Meltzer and Phillips). BBN which stands for Bolt, Beranek and Newman, is now Raytheon BBN Technologies (“Information”, Dalakov). A computer virus is a program created to cause damage to a computer or perform other malicious actions (204). The Creeper virus was designed to infect the ARPANET network. ARPANET, which stands for Advance Research Projects Agency, was established by the United States government as an agency in 1969 to provide a computer network connecting various academic and research organizations; it was the predecessor of the Internet ("Internet", Morley and Parker). The creeper wasn't really bad, the "infected computers simply displayed the message, I am the creeper: catch me if you can" the computers suffered no permanent damage (Benford 112, Meltzer and Phillips). The Creeper virus was an experiment of a self-replicating program, designed not to damage but to demonstrate a mobile application (Dalakov). Self means to do on its shelf (“Self”). To replicate means to repeat again and again in exactly the same way (“Replicate”). Both of these words are combined since Self-replicating means to copy oneself automatically (“Self-replicating”). A computer program is executable software that runs on a PC or computer system (Christensson). An executable file is a type of computer file that runs a program when opened (Christensson). Software is the instructions that tell the computer what to do (“Software”). Software is the entire set of programs, procedures and routines associated with the operation of a computer system, including the operating system...... middle of paper ...... to recover user data ("Ransomware "). This means that the criminal is using a computer by blocking your computer by transmitting your authorization to the computer. This allows you to earn millions of dollars by creating viruses and scams in less than an hour (ComputerCareClnc). In the world of computers we will never find the real answer. Why do people create computer viruses? Why do they benefit from it? It's like asking why people commit crimes? (Why people create computers). In the 20th century, at the beginning of the first computer viruses. They were for experiments, annoyance and testing. They didn't really damage computer systems or computers back then. In the 21st century, computer viruses are changing. They are becoming smarter and more destructive rarely without annoyance, but are intended to cause some damage to a computer or computer systems (Benford).
