I'm still experimenting with Clam and I've got 103.4 installed on an OEL 7.9 box.  I've got freshclam configured to download new updates every few hours.  I can manually run freshclam and successfully receive updates and I can manually run clamscan successfully.

If I run a ps command, I see /usr/share/clamav/freshclam-sleep is running so I'm assuming that this calls freshclam on the schedule.  But what is launching this on startup? 

There are no cronjobs configured.  When I look at my systemd services, I see one named clamav-freshclam but it is disabled and not running.  I expanded my search and found a total of 4 services with 'clam' in the title (clamav-freshclam, clamav-clamonacc, clamd@, and clamonacc) but none of them are running and they are all currently disabled.

Is it some other service that doesn't have 'clam' in the name?
