Welcome To AndroidCentral! Thanks for the question.

Firstly, could you let us know what phone you are using?

Many Apps today have some adverts in them to keep the cost of the app down but they normally quite subtle and not a "pop up" as you mention.

Where are you downloading these Apps from?
Always try to stay in the Google Play store.
