How to remove McAfee?

I can't find any McAfee products on my laptop but I keep getting Notifications, every 2 minutes, to turn on McAfee

Those are Safari Notifications. There is nothing to remove. Stop them by following these instructions.

• Go to Safari's Preferences (or Settings) menu > Websites > Notifications, and remove everything there.

For reference: Change Websites settings in Safari on Mac - Apple Support

Refer to Customize website notifications in Safari on Mac - Apple Support. Deselecting "Allow websites to ask for permission to send notifications" will ensure you will never again be harassed by annoying Notifications.

The following from McAfee may help you uninstall it: https://www.mcafee.com/support/?articleId=TS101226&page=shell&shell=article-view

To be clear, are you interested in uninstalling the useless "McAfee" product, or are you being harangued into installing it through a repetitive popup or Notification?
