New bootblock virus found
Hi all...
A new bootblock virus have been found on an .adf archive containing a game called 'Apple Catcher', we are not 100% sure of the name of the archive. After booting the virus changes the CoolCapture-Vector to stay resident in memory at ($000058DC). Then the virus patches the DoIO ($000059B6) Vector to infect other disks. The checksum of the bootblock changes with each mutation, so that means that there could be a lot of mutations out there. So please take care. You can read the test of 'Game Over' bootblock virus at the Virus Help Team website. Link: https://www.vht-dk.dk/amiga/desc/txt/gameover.htm Picture of the 'Game Over' virus:  Thanx to CrashDisk for his testing of this virus as well... Kind Regards Jan Andersen Virus Help Team https://www.vht-dk.dk |

Nice find, I wonder when this was actually produced? I'd be interested in seeing a commented disassembly of it (not that I couldn't do it myself, but... just in case you already had one
 ).
