Pre-release updates (the Pre-release update option) are updates which have gone through thorough internal testing
and will be generally available soon. You can benefit from enabling pre-release updates by having access to the most
recent detection methods and fixes. However, pre-release updates might not be stable enough at all times and
SHOULD NOT be used on production servers and workstations where maximum availability and stability is required.
The list of current modules can be found in Help and support > About ESET NOD32 Antivirus. It is recommended that
basic users leave the Regular update option selected by default.

Gamer mode will disable all notifications.

new profile, click the Profiles... button and then click the Add... button and enter your own Profile name. When
creating a new profile, you can copy settings from an existing one by selecting it from the Copy settings from profile
drop-down menu.
In the profile setup window, you can specify the update server from a list of available servers or add a new server. The
list of existing update servers is listed in the Update server drop-down menu. To add a new update server, click Edit…
in the Update settings for selected profile section and then click the Add button.

4.3.1.2.1 Update mode
The Update mode tab contains options related to the program component update. The program enables you to
predefine its behavior when a new program component upgrade is available.
Program component updates brings new features or makes changes to those that already exist from previous versions.
It can be performed automatically without user intervention, or you can choose to be notified. After a program
component update is installed, a computer restart may be required. In the Program component update section, three
options are available:
Never update program components – Program component updates will not be performed at all. This option is
suitable for server installations, since servers can usually be restarted only when they are undergoing maintenance.
Always update program components – A program component update will be downloaded and installed
automatically. Please remember that a computer restart may be required.
Ask before downloading program components – The default option. You will be prompted to confirm or refuse
program component updates when they become available.
After a program component update, it may be necessary to restart your computer to provide full functionality of all
modules. The Restart after program component upgrade section allows you to select one of the following options:
Never restart computer – You will not be asked to restart, even if it is required. Please note that this is not
recommended, since your computer might not work properly until the next restart.
Offer computer restart if necessary – The default option. After a program component update, you will be
prompted to restart your computer in a dialog window.
If necessary, restart computer without notifying – After a program component upgrade, your computer will be
restarted (if required).
NOTE: Selecting the most appropriate option depends on the workstation where the settings will be applied. Please be
aware that there are differences between workstations and servers – e.g., restarting the server automatically after a
program upgrade could cause serious damage.
If the Ask before downloading update option is checked, a notification will display when a new update is available.
If the update file size is greater than the value specified in the Ask if an update file is greater than field, the program
