I sincerely apologise if this has been asked previously, I searched via Google and have been unable to find an answer I understand. How does the de Broglie-Bohm, or Pilot Wave, interpretation, well interpret virtual particles. The beauty of the deBB interpretation seems to be the unity of the quantum-world and the everyday world (no magic observation mysteriously collapsing an superposition, or splitting the multiverse), but virtual particles seem so indeterminate that they provide, in my understanding, difficilty for deBB. If it helps you gauge the level of answer to give I studied physics in the UK until 18, and my university education was largely in medical biology. Though equations are appreciated for sake of completion...i doubt i will do any more than partially understand them.
