You can make backup copies of your favorite disks that were written
with a speeded up clock by slowing down the disk rotational speed
on "Joe Breaker's" machine.  I did such on mine to copy some 
nasty disks.  I have an old Amiga 1000 with NEC disk drives.  On
the bottom of said drives there is a pot to control the spindle
RPM.  Some other drives, Panasonic for instance, seem to use a
crystal controlled time base for the motor, and can not be tweaked
to copy nasty disks.

The solution is to make the software good enough that people would
rather buy a genuine copy rather than pirate something of possibly
unknown origin.  The virus scare actually works to your benefit to
encourage people to buy orginals.  We'll ignore the small number
of commercial relases came with a virus at no additional cost :-).
