Rules clarification for regionals

By Seamoose, in Android: Netrunner Rules Questions

I have been searching and looking for answers and maybe I am missing them. With regionals coming up I am however trying to get some answers to this burning question.

1. Does a parasite trash a peice of ice with zero strength if it has no virus tokens. With the reading of the card the ability states 'if it has a virus token it gets minus strength and if its strength is ever zero its destroyed.' I have literally been playing it both ways according to whatever my opponent is more comfortable with. But I cannot seem to find an answer anywhere, I think the virus token makes the cost which means the trash effect will not happen unless their is a token but I am not entirely certain.

A token-less Parasite will trash a zero strength ice.

As long as Parasite is attached, tokens or not, when this condition is met, the ICE is trashed. Period.
