Virus:The Game, v1.3 <ASP> from DynoTech Software.

A fast knuckle banging, joint challenging, finger
flying game where YOU are the Virus ("the Bad Guy").
Run recklessly about the surface of a hard drive while
eliminating each sector's critical bytes. Collect
enough bytes to venture to the next level. Watch for
the relentless pursuit of a virus cleaner disk that
chases you without restrictions!  This fast moving
puzzle-arcade game is not for slackers. It is highly
recommended for those with blazing fingers, fast wit,
and a "death wish." Defy the virus cleaner disk as
it chases you across each sector. Avoid bombs, bad
clusters, and even laser blasts as you weave from one
danger to the next. Plan your steps carefully because
each step you take reduces your playing area. As you
eat away at the surface of the hard drive you also eat
away at your own ability to move in certain sections
of the playing field. This is one virus you will want
to keep!
