Greetings From McAfee,
We would like to inform you whenever you do a purchase of new Laptop/PC. You will be getting McAfee as a 30-days trial. Once it is about to expire you will be getting pop-ups for renewal. Incase if you would like to renew the subscription, you can click on renew subscription and it will be your paid subscription.
If not, You can uninstall it from your device. However it is good to have security software in windows device for protection purpose.
If this information was helpful in any way or answered your question, please mark it as the accepted solution and give Kudos if appropriate.
