clam scanner not updating?

I’m a little confused about clamd for my system.

I have centos7 on a cloud
I have logwatch and lately I realized that it was saying virus database is out of date.

if I run clamd:
WARNING: Ignoring deprecated option AllowSupplementaryGroups at /etc/clamd.d/scan.conf:199
LibClamAV Warning: **************************************************
LibClamAV Warning: *** The virus database is older than 7 days! ***
LibClamAV Warning: *** Please update it as soon as possible. ***
LibClamAV Warning: **************************************************
ERROR: LOCAL: Socket file /var/run/clamd.scan/clamd.sock is in use by another process.

But doing freshclam doesn’t work? I get
freshclam
-bash: freshclam: command not found
If I do systemctl status clamd
Unit clamd.service could not be found.

I recall I think in the virtualmin wizard I select to have clam scan start up, scan the email and shutdown I believe? its been so long I forget. But why can’t I simply do freshclam to update its DB?
