In case a stealth virus destroys the disk, data can be reloaded with a minimum of disruption and no damage. Backups should be located both on site and off-site. Backups of all computer applications programs should be made separately from data files. The write protect feature of floppy disks which contain applications programs should be enabled. Several boot disks containing an anti-viral program should be available in the firm.
Simple procedures can sometimes be very effective.
Some organizations have old slow computers designated as anti-virus checkers in each work area. At those firms, employees must check all floppy disks which have received foreign data or which have been off the premises on the old computers which have been loaded with anti-viral programs. A clean diskette is a safe diskette. Although viruses are here to stay, an attack can be avoided or survived. Computer health, just as human health, is as much a matter of prevention as of cure.
