Updating the program

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. Regularly updating the program modules and components is an important aspect of maintaining complete protection against malicious code. Please pay attention to the product modules configuration and operation. You must activate your product by using your License key to receive updates. If you did not do so during installation, you will need to enter your License key to activate your product in order to access ESET update servers while updating.

Under normal circumstances, you will see the green check mark in the Update window, indicating that the program is up-to-date. If you do not see a green check mark, the program is out-of-date and is more vulnerable to infection. Please update the program modules as soon as possible.


Unsuccessful update

If you receive a modules update failed message, it may be caused by the following issues:

1.Invalid license – The license key has been incorrectly entered in update setup. We recommend checking that your license key was entered correctly. The Advanced setup window (click Setup from the main menu and then click Advanced setup, or press the F5 key on your keyboard) contains additional update options. Click Help and support > Change license from the main menu to enter a new license key.

2.An error occurred while downloading update files – This can be caused by incorrect Internet connection settings. We recommend that you check your Internet connectivity (by opening any website in your web browser). If the website does not open, it is likely that an Internet connection is not established or there are connectivity problems with your computer. Please check with your Internet Service Provider (ISP) if you do not have an active Internet connection.
