Forum:Standby Phase

In standby phase i know there are traps and spells can be activated in this phase. but can my Opponent activate any Trap Cards and Quick-Play Spell Cards in my standby phase or there are specific conditions for them to be activated ? I know cards like [Battle Mania] specify that it can only be activated in the standby phase so they are out of the question and. but what about cards like [Planet Pollutant Virus] or [Light of Intervention]
