something like take a supernatant from lysed cell culture (where virus has been infecting cells), and centrifuge the big stuff (or physically fractionate to get things if the size you are interested in)

what you get will be mainly protein particles with some sort of nucleic acid. you can then characterise both of those with a million techniques including sequencing, structure etc

the results you get are consistent with what a virus is supposed to be. what that actually means is a different question

bear in mind that most of human DNA is probably viral in origin by this definition. the whole thing is deep af and nobody really understands it. but pretending there's nothing there is kinda stupid
