Virus Killer !

          This  handy GEM-based utility will seek out and  destroy 
     viruses  that have installed themselves in the bootsector  of 
     your disc.  This is the most common type on the ST.  Boot  up 
     the  program,  insert a disc into the drive and and click  on 
     the  Check button.  Amessage will be printed in the  dialogue 
     window stating whether the disc is clear or  infected.  Click 
     on the Kill button to kill a virus.

          The  program  loads the first sector of the disc  -  the 
     boot  sector - and checks that the first two bytes are  zero. 
     If  they are ,  all is well.  If they aren't  the  bootsector 
     probably contains an executable program.

          Arcade  games that run automatically when you switch  on 
     have  a perfectly normal and harmless executable  program  in 
     the  boot sector and the utility may think that the  disc  is 
     infected with a virus.  Don't try to kill it or you may  ruin 
     the disc.

          Ordinary discs don't have programs in the boot sector so 
     destroy it if one is found.

          To  make sure your micro isn't infected switch  on  with 
     nothing in the disc drive and wait until the desctop appears. 
     Double  click  on VIRUS.PRG ,  insert the infected  disc  and 
     click on the Kill button.
