I don't think the question is whether viruses are real, the question is whether scientific studies have yet to show transmission of infection that leads to disease.
There isn't a scientific definition for "real" that I'm aware of. Do you know of any studies that have isolated a virus, or a virus plus host cells, and successfully introduced those into a novel population to reproduce disease? All I've ever managed to find are epidemiological studies after an assumed viral outbreak, but I really am interested to see a more controlled study that helps prove a more direct link.
