:what:You don't download and install Android Device Manager. It's included in Android by default as part of the base OS.
Click on Google Settings in your app drawer. ADM is in there. Activate it. Then open a browser, mobile or desktop, and go to: https://www.google.com/android/devicemanager
...and you can locate, lock or wipe your device.
There is also an app on Play called Android Device Manager which allows you to lock/locate/wipe other devices from your phone or tab.
That can be uninstalled, but even without the app, the core functionality is built in to Android and if setup correctly, it means your device can be remotely locked or located from any PC.
