Hi, I'm on an HTC One, running v4.2.2
Problem I'm seeing is that I'm being notified there's a new update available. When selecting it I'm asked for my pin number, This the opens an update software page with "The following 1 software upgrades are ready for you in avast! Anti-Theft 3.0.5630:" and 2 option buttons, Back & Google Play. Selecting Google Play opens the page of Update Agent, 2 options are Open, and Deactivate. Clicking deactivate and I get a message This app is a device administrator and must be deactivated. I've tried loads of options in programme settings but to no avail? Any ideas?
