Create a different kind of computer virus.

Software that works like normal software. But it is so crap the user doesn't want to use it. It is difficult to uninstall. It adds itself to every possible location. The user always sees a reference to it. As the user tries to uninstall it, it adds itself to several locations by the 4th iteration the user decides it is better leave the crappy program on their computer than risk further attmpts to uninstall.
