I Phone Spam Calls

I am thinking about getting Avast Premium for my desktop PC and I understand that I can apply Avast Premium on both of my I Phones. My wife’s I Phone gets Spam Calls daily, which she does not answer, but I was wondering if the Avast Premium would prohibit those calls from coming in?

I wouldn’t apply Avast Premium on the IPhone. It won’t prohibit scam callers coming in. Why not blocking those callers,
