License Renewal Problem - Free Version

Good morning,
A colleague has a problem with the renewal of the avast (free version) license that expires in a few days.
No renewal button appears (only for a paid license), so how she can it to renew your avast free license and continue to use it?

Thank you

Registration is history, see: https://www.avast.com/registration-free-antivirus

Thank you for your response

Perfect so it will continue to work even after expiration.

I saw this faq and I had some doubt, maybe it is better that the staff remove it.
