Regularly updating ESET NOD32 Antivirus 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.


The Advanced setup window (click Setup in the main menu and then click Advanced setup, or press F5 on your keyboard) contains additional update options. To configure advanced update options such as update mode, proxy server access and LAN connections, click Update in the Advanced setup tree.

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.
