Automatic profile switching—Enables you to assign an update profile to specific Network connection profile.

If you are experiencing difficulty when attempting to download detection engine or module updates, click Clear next to Clear update cache to clear the temporary update files/cache.

Module rollback

If you suspect that a new update of the detection engine 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.


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

icon_section Profiles

Update profiles can be created for various update configurations and tasks. Creating update profiles is especially useful for mobile users who need an alternative profile for internet connection properties that regularly change.

The Select profile to edit drop-down menu displays the currently selected profile and is set to My profile by default. To create a new profile, click Edit next to List of profiles, type your own Profile name and then click Add.

icon_section Updates

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.

Ask before downloading update—The program will display a notification where you can choose to confirm or decline update file downloads.

Ask if an update file size is greater than (kB)—The program will display a confirmation dialog if the update file size is greater than specified value. If the update file size is set to 0 kB, the program will always display a confirmation dialog.

Module updates

Enable more frequent updates of detection signatures—Detection signatures will be updated in shorter intervals. Disabling this setting may negatively impact the detection rate.

Product updates

Application feature updates—Automatically install new versions of ESET Security Ultimate.
