%%Notes: Infects .COM files. The virus replaces the keyboard handler, 
and if it is in place, it occasionally replaces the key that is typed, 
with the key immediately to the right.  The fumble only activates if you 
type at better than six characters per second (approximately 60 wpm).  
If you type at that speed, after not using the keyboard for five 
seconds, you get a fumble.  Typed characters are not what you pressed.     
v6-151: At least one anti-virus program can detect and remove Fumble.E
