     Removal      : Install Boot

     Comments     : If  you`re  starting  the  Eleni  3 virus it allocates
                    20000 byte Chip-memory as long as there isn`t any Chip
                    memory  anymore.  The the virus copies itself into the
                    last available chip-area.

                    Then  the  virus  patches  the DoIO()-Vector to infect
                    other disks. If you`re  now inserting a disk the virus
                    checks  if the disk is already infected by loading the
                    bootblock  at  address  $70000. If the disk is already
                    infected  the  virus  subs  1  from a special address,
                    which  is  on  some AMIGAS the Clock-Address (A2000, I
                    think).   But  all  this  will  be done if there was a
                    bootblock READ-Access. If a WRITE-Access is requested,
                    the   virus  patches  the  LoadSeg()-Vector  from  the
                    "dos.library".

                    This LoadSeg-patch will do the following:
                    If  a  file  will  be loaded  the virus checks for the
                    Clock Address. If this address reached the value 1 the
                    virus  insert a new name for LoadSeg, "ELENI!". In the
                    CLI you will get this error: 

                              `Unknown command: "ELENI!"`

                    If the  Clock-Address  reached  0  the virus loads the
                    actual file into address $70000 und some bytes in this
                    file will be changed. You will see a GURU.
