How are devices created ? 

[DavidR]

It is created when you link an installation to your my.avast.com account.

If you were to uninstall and reinstall it is possible that it would be considered a 2nd device.

You should be able to delete the devices from your my.avast.com account, that would remove the linkage in your current/only installation and you would have to link it to your my.avast.com account again.

What avast version (latest build 2015 10.3.2225) do you have installed free/pro/Internet Security/Premier ?
