By "virally attached", do you mean the natural reordering the DNA does to express traits based on environmental stimuli that viruses evolved from?

The most concise answer I can make to that is found here:
[freedomplatform.londonreal.tv - Interview of Zach Bush] Basically there has been a paradigm shift in medical knowledge over the last two decades that hasn't hit main stream yet, all out of genome studies. For instance, a "virus" isn't a living organism; what it appears to be is targeted data packages of DNA that is excreted by microbial organisms, germ poop. "Germ Theory" is about to take a whack. A "malaria is caused by bad air" kind of whack. Worth watching.

Yes, but originally they were from regular DNA swapping that occurs within a cell. We've known for a while that they target bacteria and replicate there and then spread to the larger organism that the bacteria lives in and infects those cells. This is why antibiotics will work to lessen a viral infection. Doctors have been prescribing antibiotics for years for this.
