Is it possible to disable clamAV at start?

[Kicey]

The clamAV using lots of server resources, and may have confict with other protector on the server. Is it possible to disable it when I start the container. Is there any way to config that?

I had the same problem, I was running a container in a kubernetes cluster. The container either consumed almost 2GB of memory, or clamav went into an eternal reboot and the container began to consume more than one dedicated core. I tried many ways, in the end I just turned off the service.
/etc/supervisor/conf.d/clamav.conf

[program:clamav]
command=/usr/sbin/clamd -c /etc/clamav/clamd.conf --foreground
priority=999
startsecs=0
autostart=false
autorestart=false
stdout_syslog=true
stderr_syslog=true

Changes:

• priority 20->999 (lower)
• autostart true->false
• autorestart true->false

To save the changes, attach the modified configuration file to the container. An example for kubernetes:

@siarheidudko Thanks for your detailed answer. I turn to use mailu (I also suggest that to you), so I can't verify it.
