I have installed AVG Antivirus Free Edition, but when I go to setting to delete it I can't do it, neither the data, only I can delete the cache.
If I go to google play and to AVG Free edition there are 2 options: open and disable. If I select disable appear "This aplications is a administrator of dispositives and you need desactivate it to unistall".
I downloaded 3º app to unistall, but can't unistall it
How can I delete it? Is a non-root device.
