Why does this happen?

When I download an app, this msg pops up:

Does anyone know how to get it to stop popping up?

Also, whenever I download an app, the Facebook app starts to download too. Started happening recently and it's very annoying.

Thanks in advance!

 

Looks legit. Have you done this yourself yet? I wanna make sure it works before doing it myself.

 

Alright, I just followed the steps and it does work. Very easy to do as well.
