Type/Size : Boot/1024

Manifestation: Pretends to be a viruskiller-boot.
Removal : Install boot.
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.
