                         The Virus was Strong !! But LSD is Stronger
                         Thanks SCA for this great Code. Hi Ozz & Rebel 
                         Servo & Storeroom Boy! Now back to the Boot!!"
                      virus feature: pressing left mouse/fire button of
                         port 1 during system reboot, causes the screen
                         to become green and the virus to shut down it-
                         self by clearing ColdCapture and CoolCapture
                         Vectors.
Type of infection...: self-identification method: testing 3rd longword
                         for matching string 'CHW!'
                      system infection: RAM resident, reset resident,
                         bootblock
Infection Trigger...: reset (CONTROL + Left-AMIGA + RIGHT-AMIGA)
Storage media affected: only floppy disks (3.5" and 5.25")
Interrupts hooked...: ---
Damage..............: permanent damage: overwriting bootblock
                      transient damage: screen buffer manipulation:
                         screen becomes black, message (see above) is 
                         shown by fading in and out peaces of it
Damage Trigger......: permanent damage: reset
                      transient damage: 15th infection
Particularities.....: a resident program using the CoolCaptureVector is
                         shut down, also when using the ColdCapture
                         Vector when the virus is shut down by its 
                         'suicide' function
Similarities........: SCA virus strain
