Updating the program

Regularly updating ESET Internet Security 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 their configuration and operation. You must activate your product using your License key to receive updates. If you did not do so during installation, you can enter your License key to activate your product when updating to access ESET update servers.


Your License key is provided in an email from ESET after purchasing ESET Internet Security.

Click Check for updates to detect the latest available version of ESET Internet Security.


Update process

After clicking Check for updates, the download will begin. A download progress bar and remaining time to download will be displayed. To interrupt the update, click Cancel update.



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 If this is not the case, the program is out of date and is more vulnerable to infection.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

If you receive an unsuccessful update message, it may be caused by the following issues:

1.Invalid license – The license key has been incorrectly entered in update setup. We recommend that you check your authentication data. The Advanced setup window (click Setup from the main menu and then click Advanced setup, or press F5 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.



We recommend restarting your computer after successful update to ensure that all program modules were updated correctly.
