Use the Anti-Virus program. If a PC has viruses, this PC may infect all the floppy diskettes used on it unless the diskettes are write-protected. The so-called boot sector viruses infect a PC when you reboot the computer and leave the diskette in the floppy drive. If your diskette is write protected, it cannot be infected. Never leave a diskette in the floppy drive unintentionally during rebooting.
Floppy disks can become bad any time.
