[comp.virus] 0 bytes in 1 hidden file, virus??

ACSJNF%DEPAUL.BITNET@VMA.CC.CMU.EDU (10/23/89)

        In reference to CHKDSK's message about 0 bytes in 1 hidden file,
        if I remember correctly, CHKDSK is probably registering the
        volume label, in which case PCTOOLS does show it (at the top of
        the screen, instead of in the file listing).

        Try installing the system onto the disk (i.e. SYS A:), and then
        run a CHKDSK.  It should register xxxxxx bytes in 3 hidden files,
        where xxxxxx depends on the version of the system that you are
        using.  Respectively, the hidden files should be:

                IBMBIO.COM -- Contains the BIOS routines
                IBMDOS.COM -- Contains the DOS routines
                (volume label)

        IBMBIO.COM and IBMDOS.COM will appear in the PCTOOLS window.  They
        will probably have the HIDDEN, SYSTEM, and READ-ONLY bits on.
        It may also have the ARCHIVE bit on.
