A computer virus is, simply, a program designed to attach itself to another computer program. Some computer viruses damage the data on your disks by corrupting programs, deleting files, or even reformatting your entire hard disk. Most viruses, however, are not designed to do any serious damage; they simply replicate or display messages. Most viruses stay active in memory until you turn off your computer.
