     Discovered   : 22 december 2020
     
     Info         : Appel Catcher is a game,  where a little man  has to catch appels falling
                    from a tree.

     Way to infect: At  launch  it  installs  it's code  in memory  and launches the original
                    bootblock to  make  it  look  like all is  well.  Unlike  other  viruses,
                    it recognizes an already infected disk.
                    
                    The  virus  injects  code (112 bytes)  into  the original  bootblock at a
                    variable  position (harder to detect!).  It writes  its code in sectors 3
                    to 5 and a copy of the original bootblock in sectors 6 to 7.

                    The virus installs it's code over  the original bootblock  where there is
                    room on the host disk.  So it does not overwrite any  data but writes the
                    virus code  into the original bootblock  is there is any empty space  for
                    the code. The virus does not infect a disk that does not have enough room
                    for its data.
