  The alleged "error setting certificate verify locations" is false:
  # sudo -u clamav -EH ls -al /etc/ssl/certs/ca-certificates.crt
  -rw-r--r-- 1 root root 186336 Mar 15 08:45 /etc/ssl/certs/ca-certificates.crt
  # sudo -u clamav -EH ls -al /etc/ssl/certs
  total 556
  drwxr-xr-x  3 root root  12288 Mar 15 08:45 .
  ...
  
  Also, it is possible to contact the website as clamav user, meaning there is 
no CA access issue for that user:
  # sudo -u clamav -EH wget https://database.clamav.net
