Scientists do not know how many viruses there are because new ones are constantly being made from old ones joining.
Even before the knowledge of science exists, these things such as viruses already exsisted.....the scientist will know in time.
virologist is a scientist that sudies viruses.

A 'virologist'.
Only a brainy scientist would know. All viruses haven't been discovered yet, you know. But I know some. Such as Calici, Picorna, Adeno, MiMi, Herpes, Poxapilloma, Polyoma ,Parvo,Ebola,Noro, Circo, Annelo, and Hepadna.
viruses do not grow, and viruses do not respond to changes in their environment. Therefore, viruses are not living organisms. All living things reproduce, but Viruses need living cells to reproduce because Viruses cannot reproduce by themselves.
Many, if not most biologists do not consider viruses living. So, they are not on any phylogenetic tree that I know of. They may have a phylogeny that I am unaware of, though.
Virology is the study of viruses and their evolution, structure, classification. It also is complexes of nuclies acids and proteins that help all living cells.
