My $0.02

I've spent the afternoon looking at the various posts and realized that viruses seem to be broadly grouped. Within a genus there are documented viruses that infect plants and animals, not exactly close taxonomically. I don't remember pathogenic bacteria, fungi or oomycetes being like this. In fact, plant pathogenic bacteria make ideal bio-weapons due to the handler not having to worry about harming themselves.  

If what I say is true, then I'm curious how this might affect our viral classification, if at all?

I could be mistaken and please correct me if I am.
