What domain is viruses classified under?

Viruses are not derived from preexisting cells, and thus oppose the Cell Theory, and are not cells; they are simply a cluster of protein and genetic material. An organism is defined as "consisting of monomeric units known as cells". If viruses are not made up of one or more cells, they obviously cannot be considered as an organism, if they are not organisms, how can they share the same system of classification as all other organisms on Earth (specifically speaking: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species)? There is also a dispute going over whether viruses are alive or not (since they cannot metabolize and reproduce independently).

I have browsed through many sites on any hint on which Domain viruses are classified under, but all they tell me is the families and genus of some viruses.

Which Domain do viruses belong to?

A good question,

A short answer is- Viruses do not fall under any domain. They are neither prokaryotes nor eukaryotes. They are not considered a part of the classical living world. Therefore, their system of classification is entirely different.

Here is my answer in detail:

This question first arose with the discovery of viruses. When the world was classifying everything under either Animal or Plant kingdoms (Two Kingdom Classification), there came these strange "living chemicals"; they could be crystallized like salt and sugar. When dry crystallized viruses were dissolved in water, they would again regain their ability to infect the host cells. They had genetic material, could evolve and adapt but, if left all by themselves, they were nothing but chemicals! Thus, came the need to revamp and redefine the whole system.
