Contact PCProtect. You have to phone PCProtect’s billing support number and request a refund. PCProtect’s website includes an email for billing support, but it no longer works.
Follow the support representative’s instructions. You’ll need to tell a support rep why you want to cancel your subscription, and after you’ve convinced them that you are really certain that you want to get rid of PCProtect, they will send you a link to unsubscribe. Once you click that link, simply click the appropriate dialogue boxes.
Wait for your refund. PCProtect will refund you within 7 days. I received my refund within 24 hours, which is better than most other antivirus companies.
