Honestly, I don't like that things can be installed on your phone without permission, even by the original providers. This is the entire reason I have auto-blocker and Max restrictions enabled. I get that it may potentially be a vital update being installed, but I'd love to know about it first. ESET is the reason I figured it out; it sent my antivirus into a frenzy, scanning it over and over to make sure it was safe. I had to research to make sure it was legit.

Found this app along with Android safety core. Both downloaded without permission, despite my phone being locked down to prevent these types of downloads. Key logging, really? I think permissions are for all query packages? I don't know what this is for but it doesn't look good and my phone has been glitching since April. Uninstalling and reviewing all settings and apps. And I guess I'm going to go through every app update, and make sure this junk isn't downloading independently

Since this was added to my phone(without my permission I might add), my Avast antivirus keeps getting turned off. I keep getting notifications from Avast telling me to turn it back on so they can protect me while I'm on the internet. I would appreciate it if you could fix this BIG PROBLEM ASAP! Update: I force-stopped the app and that seems to have solved the problem. The app has stayed off ever since.
