Not that this is really a "virus", but a piece of MIDI software
that sends out bad MIDI codes can trash some keyboards' memories.
I once built a homebrew MIDI device (a digital lab course project)
that was supposed to send out a series of MIDI codes and notes
to a Korg Poly-800 that I borrowed from a friend.  My first
attempt accidentally sent out a SYSTEM EXCLUSIVE code (I think...)
by mistake, and blanked or scrambled nearly all of the 64 presets
on his board!  He wasn't too happy about that...
