ESETS update process description

The update process consists of two stages: First, the precompiled update modules are downloaded from the ESET server. If ‘av_mirror_enabled’  is set to yes in the [global] section of the ESETS configuration file, copies (or mirrors) of these update modules are created in the following directory:

@BASEDIR@/mirror

‘av_mirror_pcu’ allows you to download Program Component Update (PCU) modules for Windows-based ESET security products. These modules can be mirrored from the ESET server.

Note: To enable the mirror and download PCUs for ESET NOD32 Antivirus, ESET Smart Security, ESET Endpoint Antivirus or ESET Endpoint Security, you have to:

set your Username and Password for update purposes (as described in the topic above),

import a license for your specific ESET product.

The second stage of the update process is the compilation of modules loadable by the ESET Gateway 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:

@BASEDIR@

This is the directory where the ESETS daemon loads modules from and thus can be redefined using the ‘base_dir’ option in the [global] section of the ESETS configuration file.
