A virus seemed like a great idea to affect/infect them all. The Borg are far from defeated as far as we know. In BoBW and FC, Picard and crew ultimately destroy only one cube in each. And Janeway destroyed a hub but not the homeworld or even a large percentage of the race.
I have always liked the idea that V'Ger was the involved in the creation of the Borg race when it arrived at the planet of living machines. Still, one of my favorite Trek "what ifs" was the proposed episode VOY episode "Origin of the Species."
