Virtual particle may "pop" into existence for very brief time period and then vanish again.. The product: (mass * delta-time) will be smaller than P2*pi() *Planck constant. In this case, the energy preservation principle is not violated. Because charge etc also has to be preserved, particles pop out in pairs (like electron and antielecton, for example).

Hi
This is one reason we could see black holes. A virtual partical pair is created just above the event horizon, one part of the pair is captured by the black hole and the other part remains outside the event horizon.
