The Mallet Virus:  Often generated by the Akane Tendo virus when it
catches the Ranma Saotome virus attempting to link to either the
Shampoo, Ukyo Kuonji, and Kodachi Kunou viruses (or so the Akane Tendo
virus will think).  Is also used to keep the Ranma Saotome virus within
operating limits.

Gambling King Virus(I think that's what it's called): Will take over
your computer and challenge you to any casino game.  If you lose it will
all your files and laugh insanely saying "I never lose!" *don't know
much about the gambling king, so bite me*
