Yesterday my smartphone was “taken over” by a weird ad that kept popping up at the top of my screen (see screenshots). If these look familiar, then this post is for you. Let me tell you how it happened.
Yesterday I received a notification from Google Play informing me that I had several pending updates. I took a quick look at the list and hit Update all.
A few hours later a banner started appearing at the top of my screen. And that kept happening whether I was using an application or when I was on the native screens (settings, home screen etc.)
Tapping the small opt out button in the right corner pointed to a tracker.tpc.re empty page. When trying to turn it off, I was redirected to the Google Ads page. The intention was to make me believe that the banner was in fact a Google ad, which was very clever.
After some research I found out that the problem was related to the application Premium Wallpapers HD. I don’t know how the malware managed to infiltrate it. What I do know, is that the ad disappeared and never popped up again after clearing data of the app.
Uninstalling it would be also a good idea. I hope this is helpful. I will update the post, if I find out more information. I don’t know if this is relevant or not, but I am using a Nexus 5 with Android 5.1.1.
