I cancelled my subscription for AVG Internet Security for an old laptop.  I keep receiving emails telling me that the automatic renewal will take place in January 2019.  How do I stop this from happening?  Am losing faith in AVG and considering other products as problems with subscriptions have been legion since you were bought over.  Will be scanning my bank account for any unauthorized payments taken.
