I have a small pile of floppy disks I store separate from my collection because they all have the Stoned virus on them. From what I've heard all it really does is move a few bytes of data elsewhere on the disk but it's frustrating because in one case it's an original PC-DOS 5.0 upgrade set. Was there a tool eventually released that corrects the moved data or will I have to hunt down an especially ancient version of something like Norton Antivirus to fix it?

Stoned is a boot sector infector, only. (There are many variants, so be careful).

Stoned essentially moves the original boot sector to cylinder 0, head 1, sector 3 on a floppy. To disinfect, you need only move the boot sector back to cylinder 0, head, 0, sector 1. This can easily be done with DEBUG if you don't have an old antivirus program. There may, in fact, (I haven't looked). But DEBUG is a dependable method that doesn't involve someone else's program.

If you have more than 96 files in the root directory of the floppy, that's not so good, because the directory tree will have been overwritten--however, the FAT will not. So you can recover the file contents if you know the names.

I've heard of the DEBUG version but I have only ever seen the listing for it. Was there never a more prepackaged solution or even a batch file passed around?

McAfee posted a simplified version of the related antivirus on multiple BBSes. It would automatically do the swap of sectors. Better hope it identified the Stoned variant correctly.

I think it is still available in many online repositories.

See if you can find scanv109.zip clean1.09.zip from some old McAfee sites. It used to be available on F-PROT, but I don't think that site's been public for a long time.

There might be something here that could help.

IBM AntiVirus for DOS (from PC DOS 7.0 / 2000) is excellent. The command line version (IBMAVSP) is small enough to fit on a 360K disk.

Oh that will work perfectly except you can't seem to find it anywhere. I might though have an older version on my PC-DOS 6 install set though.

Look here (http://cd.textfiles.com/sv/svplatinum/CDR32/) - CLEAN109 is the McAfee virus cleaner from 1992 that was used to clean STONED disks.

Here's a copy of the standalone command-line version of IBM AntiVirus for DOS:

I know it's two months later but I finally got something together I could work with and it seems two files can't extract because they are corrupt and of course, one of them is CLEAN.EXE.

That being said, IBMAVSP is doing a fantastic job de-stoning the disks. :)

Archive.org has a 1992 zip file that isn't corrupted. https://archive.org/download/mcafee-8.4b89
