Issues of concern

Unexpected renewal costs

Some commercial antivirus software end-user license agreements include a clause that the subscription will be automatically renewed, and the purchaser's credit card automatically billed, at the renewal time without explicit approval. For example, McAfee requires users to unsubscribe at least 60 days before the expiration of the present subscription^[25] while BitDefender sends notifications to unsubscribe 30 days before the renewal.^[26] Norton AntiVirus also renews subscriptions automatically by default.^[27]
