Apple notice Legacy System Notification

Hi Julian.
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.
Please refer this article for more details.

I keep receiving the following notice from Apple re my iMac:
Legacy System Extension
Existing software on your (my) System loaded a system extension signed by “AVG Technologies CZ,
s.r.o”, which will be incompatible with a future version of macOS. Contact the developer for support.

I have AVG antivirus and VPN loaded on my iMac. Please advise me what this means for me and what action I should take to ensure that I continue to receive secure protection.
Thank you.
