Play store opens when updates are available and apps open after update

Samsung Galaxy S7 Active running on android 7.0

The issue I'm having is that while the screen is on, for instance while playing a game, the Google Play Store will open up to the home screen when it informs me that new updates are available. Another issue is also while the screen is on, when apps are finished updating, they will open no matter what I'm doing on my phone. I've had a few fixes claim it's because of third party task managers. I already removed the app killer that I've been using for like 6 devices. So obviously it wasn't that. Most of the fixes lately have said that it's an issue with adware being on the device. I find that hard to be true because of how it always happens when there are new updates or an app finishes updating. I believe this to be a problem with the software since the update to messaging that brought in the chatbots.
