Depending on the type of license you’ve acquired, it was offered either as a subscription with the automatic license renewal active from the start, or you had the option to select between manual and automatic renewal prior to finalizing the purchase. If the automatic renewal is active, the subscription will renew approximately 4 weeks before the current license lapses.
You can change the renewal settings of your subscription at any time through your Avira account.
