Can I ask for help here with what I think is adware on my LG G3? Every morning and sometimes throughout the day my phone will go to a browser (today I took a screenshot and it was Firefox) and a box will come up claiming I won a prize through facebook. I know its an ad so I just back out of it. In the past there have also been messages about updating the android system, boosting the battery, etc. I run avast and malwarebytes scans and they don't find anything. Sometimes my phone just seems to act up, be slow and the screen is not responsive. I'm not sure if it's because of this issue or not. Please help or point me in a different direction if this is not the place to ask.
