On my Ubuntu 18.04 I discovered /var/lib/openvas/ which occupies almost 2 GB. I believe I tried OpenVAS long time ago and this data has left. Now trying to remove it, I reinstalled OpenVAS as Ubuntu package and purged it. I verified that no OpenVAS package remains installed. Still the folder is there. I could delete it manually but I would prefer a more clean approach instead. How to remove OpenVAS entirely?

Manually delete it. That directory you created yourself when you set openvas up so it is not part of the installation process so will not be deleted or purged by the system. It contains certificates in ./CA and ./public/CA).
