A computer virus Essay
A computer virus is much the same as a human existence virus, nevertheless whereas flu affects the human body, the wonderfully named viruses Antics, stoned, Notepad A, michealangelo all affect the computer in various ways human can carry a virus without even knowing they have it (measles has an incubation period of a couple of weeks), a piece of computer equipment such as a floppy dice may similarly be carrying a virus without knowing. Unfortunately, the virus carrier may maliciously pass the virus on, knowing that there is an infection.A virus is a computer program that is intended to copy itself to opposite programs and causes disruption to the infected equipment.
