I'd forgotten MS-DOS 6.0 included antivirus. I have fond memories of VSAFE (I think) buzzing the speaker and warning me more or less at random about something or other (it never was an actual virus). Friends who used other antivirus solutions of the time (Dr Solomon and F-Prot were two of the other popular ones amongst friends from what I remember) ridiculed it for having so many false positives but somehow for me it was reassuring to see it was "working".
