Regularly updating ESET Security Ultimate is the best method to ensure the maximum level of security on your computer. The Update module ensures that both the program modules and the system components are always up to date.

By clicking Update in the main program window, you can view the current update status, including the date and time of the last successful update and if an update is needed.

In addition to automatic updates, you can click Check for updates to trigger a manual update.


Advanced setup > Update contains additional update options such as update mode, proxy server access and LAN connections.

If you experience problems with an update, click Clear to clear the update cache. If you still cannot update program modules, see the Troubleshooting for "Modules update failed" message section.
