I'm from the Netherlands, but I don't use cwaf, don't know if it has something to do with that.
However I'm quite amused about what you're company is offering when you're a noob on Linux. Only installing DA with CSF (and maybe cwaf) is not quite enough to secure and maintain servers.
1.) Did you try to start the freshclam service manually?
Code:
systemctl start clam-freshclam.service
2.) Check if the freshclam service is enabled by default after a reboot:
Code:
systemctl list-unit-files --type=service
I might be able to help you in NL in the future, depending on the kind of problems you want help with.
