                        THUNDERBYTE ANTI-VIRUS UTILITIES


    The Thunderbyte Anti-Virus (TBAV) utilities are designed to protect
    against, and recover from computer viruses. The TBAV utilities are
    grouped in four packages, and may be registered individually. It is
    also possible to register the entire TBAV utilities (Pkg 1, Pkg 2,
    Pkg 3, and Pkg 4) as a single unit.



 Pkg 1  TBSCAN  (Consists of TbScan)
        TbScan is a generic virus scanner with many options. Identifies
        pre-existing infections of known & unknown viruses. Scans with a
        blazingly high speed DOS system, network and/or diskettes for
        viruses. Built-in fast and reliable integrity checking. Built-in
        algorithmic virus recognition through the use of AVR modules.
        

 Pkg 2  TBSCANX  (Consists of TbScanX & TbCheck)
        TbScanX is the resident companion to TbScan. Taking just 1K of
        RAM, TbScanX checks every program file before it runs. TbScanX
        also checks program files before copying, moving, or reading.

        TbCheck is a resident integrity checker. Checks the CRC and
        other vital information of a program when it is to be executed.
        Because viruses spread by changing code in executable program
        files, TbCheck will always report changes in these files
        compared with the fingerprints. TbCheck will report the presence
        of unknown as well as known viruses.


 Pkg 3  TBCLEAN  (Consists of TbClean)
        TbClean is the worlds first heuristic cleaner! TbClean makes it
        possible to remove even unknown viruses, without any information
        about the virus and without any information about the original
        file.


 Pkg 4  TBMON  (Consists of TbMem, TbFile & TbDisk)
        TbMem detects viruses that tries to remain resident in memory.
        TbFile detects any program change that indicates a virus.
        TbDisk detects any direct disk writes, format attempts, etc.



All packages include:

TbSetup   Generates Anti-Vir.Dat files used for integrity checking, etc.
TbDriver  A driver used by all our resident anti-virus utilities.
TbDel     Overwrites and delete files.
Stackman  A smart stack manager.
TBAV      Shell program for the TBAV utilities.
TbRescue  Prevents and cures partition and bootsector viruses. Can save
          and restore vital system information like CMOS.
