     Comments     : When you are starting the JeffV1.31 virus it
                    first decodes itself with a eor-loop. After
                    that it tries to allocate 3500 bytes memory,
                    makes itself resident by changing the kick-vectors,
                    installs a patch in $6c.s (Zero-Page!) and
                    finally patches the DoIO()-Vector from EXEC.LIB.
                    The DoIO()-Vector is used to infect other disks.
                    If you are inserting an unprotected disk, the
                    virus scans the root-block of it ($6E000 = only
                    DD-Disks!!!) and tries to create the virusfile
                    and to modifiy the startup-sequence. No DOS-functions
                    , like Open(), write() and so on
                    are used (!!). The virus creates the virusfile
                    with different names:
                    
                    "AddBuffers 20"
                    "Add21K" 
                    "Fault 206"
                    "break 1 D"
                    "changetaskpri 5"
                    "wait"    
                    "Arthus"
                    "Helmar" 
                    "Aloisius"

                    Sometimes the widow-title changes and following
                    messages will appear:
 
                    Ich brauch jetzt'n Bier!
                    Stau auf Datenbus bei Speicherkilometer 128!
                    mehr Buszyklen für den Prozessor!
                    Ein dreifach MITLEID für Atari ST!
                    BUTONIC!
                    Schon die Steinzeitmenschen benutzten MS-DOS...
                    einige sogar heut noch!
                    Schon mal den Sound vom PS/2 gehört???

                    Unabhängigkeit & Selbstbestimmung für den Tastaturprozessor!

                    Depending of $DFF006 , the virus gives out the 
                    following alert:

                                 Einen ganz wunderschönen guten Tag!
