You need to learn to "read" the template fragment code for /etc/freshclam.conf, in the /etc/e-smith/templates/........(and templates-custom) structures.
Note this concept will apply to any config settings that are templated and may derive from db settings.
While it may not be immediately obvious (if you are not a coder), it will become apparent especially if you look at and compare other template fragment code where you know a db setting exists.
Once you can identify code elements in template fragments, sme will become more understandable "under the covers".
