Hello. I realize there are multiple postings on this topic but none have helped me. I literally just got my phone yesterday. This is my first smart phone, I am brand new at this and still confused. I have only downloaded the following apps: instagram, pandora, facebook, tumblr & a free live wallpaper..which im sure is the culprit. I've already uninstalled it. Randomly a few hours I got a notification in my bar at the top that said "NO JOKE you have won 12,000 in gift cards" or some crap like that. I just hit the clear button and thought whatever. Then an icon appeared on my home screen that says "Cheap cars". I have downloaded Airpush detector AND addons detector. Both have said that my phone has no push ad problems or whatever. Does my phone have some sort of virus? What do I do? It's BRAND new..ugh. And how can I prevent this in the future?
