Organism
A little thought is needed about viruses. There is no agreement as to whether they should be regarded as living. They are made of protein and nucleic acid, and they evolve, which is a really important fact. However, they exist in two quite different phases. One phase is dormant, not active. The other is inside a living cell of some other organism. Then the virus is very active reproducing itself. Consider the parallel with a computer program. When in use it is active; when it is not, it is completely inactive. It is still a program all the same.
