Description
clamav releases updated definitions many times a day, we should update them more often than daily.

We could add our update script to the cron hourly directory or link the script coming from the clamav-db package in cron.daily.
If we add our script we could add some random delay inside the script to reduce the load on clamav mirrors.
We could also add a script in cron.d.

The random interval it's a best practice to avoid load on remote servers.
Proposed implementation: /etc/cron.hourly/freshclam-random
#!/bin/bash /bin/sleep $[ $RANDOM % 900 ] && /etc/cron.daily/freshclam

After updating freshclam is run every hour, but I suspect that the random sleep is expressed in seconds instead of minutes.
/bin/sleep $[ $RANDOM % 5 ] && exec /etc/cron.daily/freshclam
Evidence from logs that freshclam is run every hour:
