so this pop-up appears even though I'm not doing anything and not even on the net and it has a background of google sometimes and it says that 'google has detected viruses' on my phone and battery and such out of no where and somehow now whenever I click on an app before launching it , it takes me to the app store to download an app mainly games.
This pop up appears saying there's a virus or trojan on my phone.
Other info: Galaxy S5, battery keeps dying out of nowhere even though I'm not on the web or using the phone.
I even get a notification sound from my phone when it's locked. How to get rid of it?
