Want to cancel free trial and consequent subscription

I have taken up a 30 day free trial, with subscription to follow, but I want to cancel it. I don't want to end up paying for a subscription for avg as it is causing websites to disappear and keeps giving me pop ups about threats but won't resolve them.
