I open this post to discuss about clamav and its process.
First, im running on Hestia 1.9.2. My server don’t needs or uses any email services so i disabled most email services in /url/local/hestia/conf/hestia.conf except exim4.
For clamav, I specifically set ANTIVIRUS_SYSTEM='' as specified in another post in the forum.
After a restart yesterday, clamav has been running since then, but is not shown either in the service list in web panel or in v-list-sys-services
