Update

Regularly updating ESET Mail Security is the best method to maintain the maximum level of security on your computer. The Update module ensures that the program is always up to date in two ways, by updating the virus signature database and system components.

Click Update in the main program window to view the current update status of your system, including the date and time of the last successful update. The primary window also contains the virus signature database version. The update version number is an active link to information about signatures added in the given update.

Click Update now to check for updates. Updating the virus signature database and updating program components are important parts of maintaining complete protection against malicious code.

Under normal circumstances, when updates are downloaded properly the message Update is not necessary - the virus signature database is up to date will appear in the Update window. If this is not the case, the program is out of date and more vulnerable to infection.

Please update the virus signature database as soon as possible. Otherwise, one of the following messages will be displayed:

Virus signature database is out of date - This error will appear after several unsuccessful attempts to update the virus signature database. We recommend that you check the update settings. The most common reason for this error is incorrectly entered authentication data or incorrectly configured connection settings.

The previous notification is related to the following two Virus signature database update failed messages about unsuccessful updates:

Invalid license - The license key has been entered incorrectly in update setup. We recommend that you check your authentication data. The Advanced setup window (press F5 on your keyboard) contains additional update options. Click Help and support > Manage license from the main menu to enter a new license key.

An error occurred while downloading update files - This can be caused by 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.
