                    A NEW GENERATION OF VIRUS
                    CREATED IN SWEDEN BY MICROSYSTEMS      

     Comments     : The  Microsystem  is a very  old bootvirus. It only
                    works with  kickstart 1.2  because it  jumps direkt
                    into  the  ROM. To stay resident the virus uses the
                    Cool & Cold-Vector. To infect other disks the virus
                    patches  the DoIO()-Vector,  additionally the virus
                    changes the FindTask()-Vector.  This Vector is used
                    to set the Cool & Cold-Capture to the virusvalue.
                    Depending of infections the virus gives out an GFX-
