Also Known As:

Systems Affected:

Green_Caterpillar is a virus that infects one command (.COM) and one executable (.EXE) file on the current drive every time a DIR or COPY command is executed. As a result, those commands take much longer than normal to run. Green_Caterpillar also produces an animated caterpillar that munches text on the screen, similar to the Centipede arcade game.
