Infection by a stealth virus is a possibility, but simply regular FAT
corruption is a much more likely explanation.  Do the following:

    reboot from a clean diskette

    rerun CHKDSK

    if it reports that the file sizes are wrong, you just have regular
    FAT corruption.  In that case you can try to run CHKDSK /F and
    then replace the damaged files, just to be 100% safe :-)
