That's contradictory. Either viruses are specific RNA/DNA carriers, able to infect and reproduce within the host causing particular pathology or they are what you said - extracellular vesicles and exosomes which can't reproduce, hijack cells and infect other organisms. They are simply cell-garbage.
No, what I am saying is that they are functionally the same, they all can reproduce, hijack cells and infect other organisms and also produce new proteins, etc. it is very similar to sexual selection where DNA is exchanged.

So what's causing the pathology?
