     Rating       : Less Dangerous

     Kickstarts   : 1.2

     Damage       : The  new  installed  patch  in $68 (Zero-Page!) always
                    registrates  if you are pressing a key or mousebutton.

                    The CODER-virus is a very simple one. To stay resident
                    in  memory  the  virus  uses  the  KICK  vectors.  For
                    Infection  the  virus  uses the DoIO() vector from the
                    exec.library.   Additionally  it patches the Zero-Page
                    ($68).  This  interrupt  will be used if you press any
                    key (or button).
     Manifestation: Pretends to be a viruskiller-boot

     Visible text : Your computer is stoned! Legalize Mariuhana!  Parasite

     Comments     : The  virus  copies  itself  always  to the same memory
                    address ($7F600).  There is a crypted text in the boot
                    block,  which the virus decrypts to $7FA00.
     Info         : Again. Only the text has been changed.
