BitDefender provides updates for its antivirus programs to users with BitDefender subscriptions. BitDefender subscriptions automatically renew by default, charging the credit card associated with your purchase. While the auto-renew feature ensures your subscription is always current and that you have the latest updates for BitDefender, if you've switched to a new antivirus program you won't want to renew your BitDefender subscription. You can cancel the automatic renewal feature from the Contact Us page on the BitDefender online store. After you cancel automatic renewal, you can continue to receive updates for BitDefender until your purchased subscription time expires.
