How to Activate Antivirus: Subscription and Renewal Help
Published by 
Ayush Patel · Updated
Use the antivirus publisher’s own activation process for the product you purchased. Keep the new-license or renewal distinction clear before applying the entitlement.
Confirm the installed product
Record the exact security product, operating system and current subscription status. Make sure the order covers the intended devices and region. If it is a renewal, complete the publisher’s eligibility checks for the existing entitlement.
Use your publisher account
Download the application from the publisher and follow the instructions supplied for the selected offer. Keep recovery access in your own account. Do not send account passwords or complete activation keys in public support messages.
Check the result
Verify the subscription end date, device coverage and protection status after activation. If those details do not match the order, keep the receipt and send support the order reference and a redacted error screenshot. Avoid applying multiple unrelated keys while the first issue is being investigated.
