Introduction to Computers. A computer is a man made electronic machine which stores, reads and processes data to produce meaningful information as output. It works very fast and does not make mistakes but its capacity is limited. It is made of English word 'to compute'. It operates under the control of a set of instructions that is stored. The genesis of computer viruses started in early 1980 when some researchers came up with self-replicating computer programs. In 1984, Dr. Cohen provided a definition for computer viruses. Here is Cohen's informal definition of a computer virus: A virus is a program that is able to infect other programs by modifying them to include a possibl A computer virus is a program that spreads by first infecting files or the system areas of a computer or network router's hard drive and then making copies of itself.
