Diamond.1063

Description Diamond.1063

These are memory resident parasitic viruses. They hook INT 8, 21h and write themselves to the end of COM- and EXE-files at their loading into the memory. The viruses return "decreased" file length on calling two DOS functions: FindNext and FindFirst FCB. Some time after activation they launch several balls of different colors, randomly moving around the screen (effect is similar to ball movement in the "Ping-Pong" virus case).
