Hmm. I have never used cron events such as @reboot
and I don't have a file /etc/clamav/clamav_opts
I was expecting a script /etc/cron.daily/freshclam but I must
have written mine myself (though anacron would use such a file).
Are you using Ubuntu clamav .deb packages or ones from ClamAV ?
Reading about @system cron events, I would not use it to
update the clamav database. Instead I would rely on anacron
noticing that we missed running freshclam at the proper time,
so start it now if appropriate.
That or stick with the clamv-freshclam daemon/service.
