I was putting together a socket 7 with Dos 6.22 already on the hard drive and noticed I could read 3.5 floppy disks that already had data on them but it wouldn't if there was nothing on them so I tried formatting them in dos and this worked I could format them but straight after it said "general failure reading drive A, abort, retry, fail?" I tried formatting a couple on my windows 10 PC because I knew the floppy disks and floppy drive were good and working and Kaspersky did a virus scan of the floppy and it found Virus.Boot.NYB
I tried to resolve it with Kaspersky but it said "cannot disinfect the detected object due to internal error" I guess Kaspersky cant write to the MBR of the floppy, I was able to format the floppy on windows 10 and a Kaspersky scan later it did not find the virus
Does formatting in Win 10 using a USB floppy drive overwrite the MBR? I'm now going to start a fresh and format the dos hard drive and rewrite the MBR but is there a way to "clean" Virus.Boot.NYB from the hard drive and floppies in dos as I might have to go through my other two systems a 486 and Win 98se and maybe Win XP not to mention about 6 boxes of floppy disks
F-PROT used to detect NYB as B1, but the virus was renamed in February 1996 (F-PROT 2.22) is F-PROT still the best dos virus cleaner?
EDIT: I tried a floppy that I formatted and virus scanned from my win 10 PC in my dos socket 7 build and it is reading it properly as empty but there is no error about "general failure reading drive A, abort, retry, fail?", I write protected the floppy first so it doesn't get NYB again
