OpenVAS is no longer included by default with Kali Linux. To setup OpenVAS perform the following steps. make sure you have the repository available in sources.list file.
nano /etc/apt/sources.list
And make sure the following line is present. If it is not, add it.
deb http://http.kali.org/kali kali-rolling main non-free contrib
You can now install OpenVAS with the following commands:
apt update
apt install openvas
openvas-setup
The openvas-setup command takes awhile to complete, so do not become impatient. When it finishes running, be sure to copy the password into text editor and save. Now you need to rebuild your OpenVAS database with the following command:
openvasmd –rebuild
This command will also take awhile to complete. Once it completes, you can access the web interface at https://localhost:9392. The username is admin and the password previously saved.
