Plenty of people use the terms "malware" and "virus" interchangeably, but they're not quite the same. A worm is very similar to a computer virus in that it is self-replicating and subverts a system; however, it usually is a self-contained program that enters a system via regular communication channels in a network and then generates its own commands. [2] If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses. It was launched surreptitiously from an MIT computer by graduate student Robert Tappan Morris at Cornell University, and spread to internet-connected computers running the BSD variant of UNIX. Viruses are known to infect nearly every type of organism on Earth.
