To provide the highest possible security for the end user, the ESET team continuously collects
virus denitions from all over the world–new patterns can appear within the virus signature
database in very short intervals. For this reason, we recommend that updates be initiated on a
regularbasis.Tospecifytheupdatefrequency,the‘av_update_period‘optionmustbedenedin

7.2. ESETS update process description
The update process consists of two stages: First, the precompiled update modules are
downloadedfrom the ESET server. Iftheoption‘av_mirror_enabled‘is presentin the [global]
sectionoftheESETScongurationle,copies(ormirror)oftheseupdatemodulesarecreated
in the following directory:

[update]sectionoftheESETScongurationle.ThenewlycreatedMirrorthusservesasafully
functional update server and can be used to create lower (child) Mirrors. However, the following
conditionsmustbefullled.First,theremustbeanHTTPserverinstalledonthelowercomputer
where the modules will be downloaded from. Second, the update modules to be downloaded by
other computers must be placed in the following directory:
/http-serv-base-path/eset_upd
where‘http-serv-base-path‘ is a base HTTP serverdirectory path–thisis the rstplace the
update utility will search for update modules.
The second stage of the update process is the compilation of modules loadable by the ESET
Mail Security scanner from those stored in the local mirror. Typically, the following ESETS loading
modules are created: loader module (em000.dat), scanner module (em001.dat), virus signature
database module (em002.dat), archives support module (em003.dat), advanced heuristics
module (em004.dat), etc. The modules are created in the following directory:
