I'm on the Samsung galaxy tab 3 running kitkat. Recently while looking though apps manager I noticed almost all my apps have permissions to sensitive data and security. This set off a huge alarm in my head since I have never seen this before, also apps being granted permissions from other so called "system apps". My guess is some kinda of virus, no idea how I got it, so I deleted all downloaded apps and attempted to uninstall apps that I was unfamiliar with. Most of the apps I have never seen before I can not remove or turn off and a factory reset did not remove them either. I'm at a loss any help would be great!
