I have a free 60 trial of AVG TuneUp on my main device. I have installed this on my second device, but when I try to use it on my second device it asks me try it for 60 days and asks me to sign up with credit card details etc. I do not want to end up paying two subscriptions after the free trial ends. What can I do? I have a paid subscription to AVG Internet Security and this works on both devices.
