The Hard Drive Virus is a green snake of binary code. He appeared in Hard Drive Courage when Courage and Muriel got sucked into Computer when he had a virus. However, The Monster Hard Drive, himself, had a cold. He loves vinegar, looks a bit like Mustafa al Bacterius from the episode Mission to the Sun, and says that he tried Artichoke Syrup Soup to cure his sickness, though it didn't work. Courage used Muriel's special gelatin instead, curing his sickness, and so he could breath and laugh again .
