Description
Computer viruses in the early days of personal computing were almost exclusively passed around by floppy disks. Floppy disks would be used to boot the computer and, if infected, would infect the hard drive files, as well. Although floppy drives have fallen out of use, it is still a good security practice, whenever the antivirus software allows, to enable the scanning software to scan a floppy disk for boot viruses.
