I think my s6 has a bug. Nearly every time I do anything on it, it throws me onto Chrome with a pop up that says either a virus is attacking my phone and I need to press ok to download antivirus app or my Facebook page has been chosen as a winner, press ok to get m prize. It's accompanied by the phone buzzing. Can anyone help me? I haven't even had my phone a month yet and purchased through Verizon.
