virus to avoid illegal copy.... please help

Well about polyboot 512... I need that virus becuase I think (yes I use
to do that) that could help to fight agains illegal copy from my
software... actually I am using license control software to distribute
my software along with the hole pc.

my BIG problem is that my copy protection scheme could easyli be
defeated using drive image 2002 and because the research I made about
how this product works I discovered that if the MBR from the hard drive
is encrypted it wont be able to work resulting in a more secure copy
protection system for me

thanks for any help sugestions and comments.
