Huge Pokemon Diamond Pokemon problems, please help!!!? - how to get rid of question mark codes for pokemon in pokemon platinum

Ok, I have a Action Replay DS and I have some code and suddenly I have 3 Question Mark Pokemon in my pocket, I can be up to 6 Pokémon. I can only lead to 4 now pokemon. I thought it was pokerus virus, and I read on the Internet, as they said to get rid of him, and he remained in a few days and a week ago and are still there, and its pissing me off wrong! Who knows how to get rid of them or give me a code for Action Replay to get rid of them, thank you.
