The update profile that is currently in use is displayed in the Update profile drop-down menu. To create a new profile, navigate to Profiles tab and click Edit next to List of profiles, enter your own Profile name and then click Add.

If you are experiencing difficulty when attempting to download virus signature database updates, click Clear to clear the temporary update files/cache.

Outdated virus signature database alerts

Set maximum database age automatically Allows to set maximum time (in days) after which the virus signature database will be reported as out of date. Default value is 7.


If you suspect that a new update of the virus database and/or program modules may be unstable or corrupt, you can roll back to the previous version and disable updates for a set period of time. Alternatively, you can enable previously disabled updates if you had postponed them indefinitely.

ESET Endpoint Antivirus records snapshots of virus signature database and program modules for use with the rollback feature. In order to create virus database snapshots, leave the Create snapshots of update files switch enabled. The Number of locally stored snapshots field defines the number of previous virus database snapshots stored.

If you click Rollback (Advanced setup (F5) > Update > General), you have to select a time interval from the drop-down menu that represents the period of time that the virus signature database and program module updates will be paused.


For updates to be downloaded properly, it is essential that you fill in all update parameters correctly. If you use a firewall, please make sure that your ESET program is allowed to communicate with the Internet (for example, HTTP communication).

By default, the Update type is set to Regular update to ensure that update files will automatically be download from the ESET server with the least network traffic. Pre-release updates (the Pre-release update option) are updates that have gone through thorough internal testing and will be available to the general public 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. Delayed update allows updating from special update servers providing new versions of virus databases with a delay of at least X hours (i.e. databases tested in a real environment and therefore considered as stable).

Disable notification about successful update – Turns off the system tray notification at the bottom right corner of the screen. It is useful to select this option if a full screen application or a game is running. Please note that Presentation mode will turn off all notifications.

Update from removable media – Allows you to update from removable media if contains created mirror. When Automatic selected, update will run on background. If you want to show update dialogs select Always ask.

The Update server menu is set to Choose automatically by default. The Update server is the location where updates are stored. If you use an ESET server, we recommend that you leave the default option selected.

Updating from Mirror

Authentication for update servers is based on the License key generated and sent to you after purchase. When using a local Mirror server, you can define credentials for clients to log in to the Mirror server before receiving updates. By default, no verification is required and the Username and Password fields are left empty.
