Random play store ads

My droid turbo keeps opening google play store randomly when operating the phone. I installed the premium version of this app to fix it but I get nothing and nothing has changed very frustrated. Please help

Same thing happening to me. I open messages or whats app and the play store opens to random apps to download.
I’ve had malware warnings pop up from avast a couple times but when the Play store opens there’s no warning.
Nothing found on virus scanner is boot scan available on mobile for Android?

Hey guys, could you please specify what type of device, app and android versions you have, or if your ROM has been modified? Thanks!
