the link give you this info…
"For instructions to disable auto-renewal of your Avast software subscription, refer to one of the following articles according to the distributor you purchased the subscription from:

Disabling the automatic renewal service for Avast orders distributed by Digital River
Disabling the automatic renewal service for Avast orders distributed by Nexway
If your order was processed by Allsoft (Softline Group company), contact Allsoft directly to cancel auto-renewal."

HOW DO I KNOW WHO THE AUTO RENEW IS WITH…WHY CAN AVAST NOT STOP THE RENEWAL…I AM SORRY I TRIED THE CLEAN UP…AND I DO NOT WANT TO RENEW IT…IT SEEMS AVAST HAS THERE OWN PROBLEMS WITH THEIR SOFTWARE…HOW DO WE KNOW IF AVAST PREMIUM HAS A BACKDOOR?..

Look at your administration to see who processed the payment.

avast can and will cancel the auto-renewal if you ask them to do so.

The backdoor was not in software from avast as they didn’t owned Piriform when CCleaner was compromised.
