Not able to update database in ClamAV with freshclam on CentOS7

Question

I'm running a CentOS freash out of Azure, with ClamAV installed on it, by running the following commands:

  yum install -y epel-release
  yum install -y clamav

When installed, I'm running the following command to update the various databases: freshclam

I get the following output (Last part of the output):

ERROR: Database test FAILED.
ERROR: Unexpected error when attempting to update database: daily
WARNING: fc_update_databases: fc_update_database failed: Test failed (8)

I find it weird that no other has had the same issue using the distro, as I have not any super specific steps, just followed steps from the page. Hope someone is able to help me...

I have the simmilar OS in my environment, I got everything to work by running the below commands:

    yum install -y -q  epel-release
    yum install -y -q clamav-server clamav-data clamav-update clamav-filesystem clamav clamav-scanner-systemd clamav-devel clamav-lib clamav-server-systemd

    setsebool -P antivirus_can_scan_system 1

    sed -i -e "s/^Example/#Example/" /etc/clamd.d/scan.conf
    sed -i -e "s/^Example/#Example/" /etc/freshclam.conf

    sed -i 's/^#LocalSocket \/run\/clamd.scan\/clamd.soc/LocalSocket \/run\/clamd.scan\/clamd.soc/' /etc/clamd.d/scan.conf

    freshclam

    systemctl enable clamav-freshclam.service
    systemctl start clamav-freshclam.service
    systemctl enable clamd@scan
    systemctl start clamd@scan

Note: If freshclam still won't update the database, it might be that your host does not have enough ram (try with at least 1,5GB of ram)
