Hello, We are a team from Microsoft Azure running ClamAV on small Linux VMs, and due to business and cost reasons we cannot use larger VMs. Peak memory usage of ClamAV is between 1.2GB and 1.5GB, which is unsustainable on our VMs, and we are looking for ways to reduce this. There are some tips to reduce memory usage in the Docker section of the documentation (Docker - ClamAV Documentation<https://docs.clamav.net/manual/Installing/Docker.html#memory-ram-requirements>) although if I understand correctly the 1.2GB load is unavoidable even with the suggestions listed on this page.
We have been told that one possibility is to remove all virus signatures that are Windows-specific, which would reduce the memory footprint to about 300 MB. Elsewhere on the ClamAV FAQ I see a few different ways to add signatures to the database but none about taking a subset. Would this be something you support or recommend for our use case? If not, are there alternatives we can consider to reduce the memory footprint of ClamAV well below 1.2GB? Thank you, Mikhail
