You got this virus from a floppy I would assume all the floppies that you have are infected you need to go to Bootdisk's and create a new bootdisk by doubleclicking the downloaded file with a floppy in the drive then write protect it by sliding the tab so you can see through both holes do this on any computer except the infected one or any other computer any of your floppies have been into boot with new floppy and do my previously suggested commands
