How to uninstall AVG which isn't listed under My Apps?
If you don't want to root your device, you should be able to see AVG under the 'All' tab in your list of apps.

If this is the case, open it and there will be one or both of these options available:


'Uninstall Updates' which will reduce the app size and save you space.
'Disable' which will prevent the app from running and will hide it from the app drawer. This will not save you any space as the app will remain on your system.


If you choose to disable it, clearing the data and cache will also save you some extra space.
