uninstallation - How can I delete AVG Antivirus on my Xperia Z1?

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.

Thanks

You need to go into Settings > Security > Device administrators and uncheck the box next to the AVG app. You will then be able to uninstall the application normally.
