The latest view for the origin of viruses is
These have arisen from nucleic acid and protein found in primitive soup
These arose from some bacteria as a result of the loss of cell wall, ribosome, etc
These arose from some bacteria, which had developed a nucleus only
These are modified plasmids, which are infact the fragments of the nucleic acids of the host
