AVG? I can't trust any of their apps due to privacy concerns. If you know how much data you "lose" at their flashlight on Google Play...
Lisandro,
Maybe you should have checked the amount of permission required to install their flashlight App.If the permission this app requires is anything beyond access to your camera, I'd get rid of it. A flashlight app also doesn't need to be very large in size. If the one installed on your smartphone is large, it's probably not what you want and probably does a lot more than simply provide you with a flashlight function. I suggest that it be removed.
I personally use the following Smartphone Flashlight App:
