I added avast thru a different, sideloaded app store than the pathetic version on the nvidia shield which has nothing from avast & it seemed to run fine, as did secure line which I also installed via the same method. Are you saying its not really doing what it says it's doing? I'm genuinely interested in your response as it certainly SEEMS to work & allows content streaming from geo blocked areas though maybe I've been lucky or something ykno but it shows in my devices as installed or did till it ran out yesterday so I'm interested in the response as it will help me decide if I'm renewing or not. Thanx in advance
