This website provides users with complete instructions on how to cancel Mcafee Livesafe Subscription and Total Protection. To do this, you have to disable the Auto-Renewal feature and then cancel your McAfee account. But to cancel your McAfee account or get a refund, you need to contact McAfee Customer Service. If you are unaware of whether you had an active McAfee subscription, or if the McAfee product is no longer needed, disable the Auto-Renewal.
