there is only some differences, that makes it, between the virtual and real particle, the virtual particle is not allowed to escape with observable energy, it must come back and return the energy packet. That is not the case with a real particle. A real particle can escape wherever it can and must satisfy all laws of Physics, if it escapes it must do so through all the known mechanisms with their known/uncertain branching rates. Virtual particles are like a “speculative tract, that might have existed”. Real particle must exist, Real particles make real effects and virtual particles make unacceptable effects. virtual particle is good only if the reasoning is good. real particle is as good as they get. by the way every real particle can be thought of as a virtual particle, just a trick as long as the calculations are legitimate. It’s not a replacement for a real particle or a process.
