Hardware realization is the use of hardware based emulators. These emulators are used to keep old software and games running. Basically it is when you make your computer run a simulation as though it is running with the specifications of an older system.

Viruses by nature destroy software, not hardware. But, you could run a "virus" that was an infinite loop, that did not allow for its termination, and that could possible lead to heat issues for the hardware. Possible damaging it.
