Small but insidious piece of programming-code that attacks computer and network systems through 'contaminated' (infected) data files, introduced into a system via disks or internet. As a digital equivalent of biological microorganisms, it attaches itself to the target computer's operating system or other programs, and automatically replicates itself to spread to other computers or networks. Invented in 1960s as a prank, viruses come in thousands of typesand versions with new ones being invented every day, each requiring a different cure (see antivirus and vaccine).
