Legacy extension error

My mac update tells me that future updates will not be compatible with AVG. Where is the AVG patch to resolve this??

Hi Ray, 

Thank you for reaching out to us and for the screenshot.

We are aware that the Apple guidelines for software developers are changing and we are actively working to improve our products so that they are fully compliant with the upcoming changes. Our transition from kernel extensions to Endpoint Security and Network Extension frameworks is expected to be ready in time for the next major macOS release.

For more details about legacy system extensions, refer to the following announcement from Apple:
