     Comments     : The Megamaster-virus is a very simple and stupid
                    one. If you are booting with an infected disk the
                    virus only copies itself to address $7F300. After
                    copying the virus sets the coolcapture-vector to
                    the virusvalue to stay resdient in memory. In the
                    virusbootblock you can read: "MGM89" (see alias)
                    There are two crypted areas: a GFX-Message-Routine
                    and the infection routine. To infect other disks
                    the virus uses the DoIO()-Vector. Sometimes, during
                    a reset, the virus decryptes the GFX-Area and show
                    this message:

                                      "Surpise!!!"
                               "Your Amiga is controlled by"
                                      "MEGAMASTER"
