Hello everyone,
May I ask for your experiences with the latest update of ClamAV with eCAP
adapter enabled. Running Squid 5.7 on Ubuntu 20.04.
Starting from today (01-March-2023) the following crash stops Squid process.
For ClamAV eCAP adapter support, please use that adapter support
channels rather that squid-users: https://www.e-cap.org/support/
It may help if you define "crash" more precisely when following up there.

Am I correct to think the crash might be related to some definition file update
issued by ClamAV team?
It might be. In the past, the changes in the ClamAV database file
location and/or name resulted in crashes with similar symptoms as
detailed at https://bugs.launchpad.net/ecap/+bug/1426095
That information may no longer be relevant, but according to the triage
of that (very old!) issue, you may want to enable Squid debugging and
search for errors like the following:
LibClamAV Error: cl_load(): No such file or directory:
/usr/local/clamav/share/clamav
HTH,
Alex.
