- Comments : The CODER-virus is a very simple one. To stay resident
- in memory the virus uses the KICK vectors. For
- Infection the virus uses the DoIO() vector from the
- exec.library. Additionally it patches the Zero-Page
- ($68). This interrupt will be used if you press any
- key (or button).
-
-
- In the Bootblock you can read:
-
- "Bootblock installed with 'CODER' the ultimate"
- "viruskiller !!"
-
-
- The virus copies itself always to the same memory
- address ($7F600). There is a crypted text in the boot
- block, which the virus decrypts to $7FA00. There you
- can read this text:
-
-
- "Something WONDERFUL has happened !! your Amiga"
- "is alive and it is infected with the"
- "'Coders Nightmare Virus'. - The ultimate key-"
- "killer, masterminded by the megamighty Mr. N"
- "of PowerBomb Systems !!"
-
-
- The new installed patch in $68 (Zero-Page!) always
- registrates if you are pressing a key or mousebutton.
- If the registrator-value reaches 2560 you get a RESET.
