Also, the fact that it cannot be disabled is also very suspect. No true Android system app has ever contained ads that I have seen, so this is very fishy.

Additionally, this "Boost" app that has installed itself on my home screen is full of ads. My phone is lagging and other apps are crashing or not performing well since I installed this app. The original File Manager app appeared alongside this app for a while, but the original app was recently removed and no longer shows up. There is no way to uninstall it or disable it. That is what makes me think this app is really malware posing as a true system app and tricking Android into installing it. It never sent me twice-daily notifications to 'clean my system', 'boost my phone' or 'free up RAM'. It never interfered with anything I was doing. The original File Manager app that shipped with my Android was very unobtrusive and was located in the Settings app on the phone. Now it's filling my lock screen with spammy looking notifications, prompting me to "boost" my phone to free disk space and memory. Seeing that the app was listed as an update to the "File Manager" app, I assumed it was safe and downloaded it. I installed this app after I received a notification on my lock screen informing me that a new system app was available for download.
