Welcome to the forums!

While I will leave this for someone else to confirm, it sounds like you have a virus. It seems to have gained access to your phone via an exploit (older Android versions have a few of them)

My recommendation is to take the phone to your provider and have them flash it via Odin to stock.

Hope that helps, and good luck!
