How do i cancel my avg tuneup 60 day trial?

i installed tuneup with the 60 day free trial but when i tried to cancel the trial i couldnt find it in my subscriptions, can AVG cancel the auto-renewal so i will not be charged ? i cannot find my subscription anywhere where i can cancel it, i can only see it on my AVG TuneUp program where it can't be cancelled from .
