This app appears to have been renamed from the predecessor, CLEAN MASTER, which was a superb app, which set trends in the industry. This filemaster, is a knockoff, with redundant notifications, that are used to make the app seem as though it's pertinent, when in all actuality, it's nothing more than a decoy, in my opinion. The "VIRUS FOUND IN YOUR SYSTEM" "ad" is fraudulent and intentionally misleading people 2 think their devices are compromised, & they're not. UNINSTALLED TODAY.
