Uninstalling broke Network Location Awareness Service on Windows 7

I uninstalled Avira Free and it broke the Network Location Awareness Service, I didn't do anything else, so it was Avira.

It doesn't start, and nor do so all dependant services, and if you want to start it manually it throws the error -1073741288

The only way to make NLA work is adding NETWORK SERVICE and LOCAL SERVICE to the Administrators Group, but I don't wan't to do that.

Because of this hack to fix it, it's obvios Avira changed some permission somewhere, the problem is who knows what is it...

Can you please help me with this?
