A pop-up appeared on my phone stating:
You only have to install a Great App to get your phone fully functioned.
The only option I am given is "Confirm."I accidentally hit the confirm button and another popup appeared stating that the install was blocked. It appears that the initial pop up is powered by the "Yellow Booster" app. I tried restarting my phone but it reappeared again.
How do I avoid this, as it seems very suspicious to me.
