So I am pretty sure I have a virus...I turned off my phone and when I restarted it I have adds in the drop down menu. You can mark them as read or w.e., but they come back periodically so I know there is some kind of virus on my phone. I havent downloaded new apps in weeks so i have no idea which one caused it. My friend also has the exact same one on her phone. I know a factory reset will get rid of it, but is there anything I can do before having to resort to that?
