Anti-malware database update

for Windows, macOS, and Linux

Updating the databases and application modules of Kaspersky Endpoint Security ensures up-to-date protection on your computer. New viruses and other types of malware appear worldwide on a daily basis. Kaspersky Endpoint Security databases contain information about threats and ways of neutralizing them. To detect threats quickly, you are urged to regularly update the databases and application modules.

Your computer must be connected to the internet to successfully download the update package from Kaspersky update servers. By default, the Internet connection settings are determined automatically. If you are using a proxy server, you need to configure the proxy server settings.

While performing an update, the following objects are downloaded and installed on your computer:

Kaspersky Endpoint Security databases. The application databases include virus and malware signatures, descriptions of network attacks, databases of malicious and phishing websites, and other data. Protection components use this information when searching for and neutralizing infected files on your computer. The databases are constantly updated with records of new threats and methods for counteracting them. Therefore, we recommend that you update the databases regularly.
In addition to the Kaspersky Endpoint Security databases, the network drivers that enable the application's components to intercept network traffic are updated.
Application modules. In addition to the databases of Kaspersky Endpoint Security, the application modules are also updated. Updating the application modules fixes vulnerabilities in Kaspersky Endpoint Security, adds new functions, or enhances existing functions.

If the databases are obsolete, the update package may be large, which may cause additional internet traffic (up to several dozen MB).

Information about the current state of the Kaspersky Endpoint Security databases is displayed in the main application window or the tooltip that you see when you hover the cursor over the icon of the application in the notification area.

Database Update task settings for Pro View

Settings	OS	Description
Run mode	`Windows` `macOS` `Linux`	At application startup. In this mode, the application checks the update source for availability of new update packages with a certain frequency. The frequency of checking for the update package increases during virus outbreaks and decreases when there are none. After detecting a fresh update package, Kaspersky Endpoint Security downloads it and installs updates on your computer. By schedule. In this update task run mode, Kaspersky Endpoint Security runs the update task in accordance with the schedule that you have specified. If this update task run mode is selected, you can also start the Kaspersky Endpoint Security update task manually. Manually. This update task run mode allows you to manually start the update task.
Run skipped task	`Windows` `macOS` `Linux`	If the check box is selected, Kaspersky Endpoint Security starts the skipped task as soon as it becomes possible. The task may be skipped, for example, if the computer was off at the scheduled task start time. When the application gets an opportunity to execute missed tasks, it runs the tasks randomly within a certain time interval to distribute the load on the computer. If the check box is cleared, Kaspersky Endpoint Security does not run skipped tasks. Instead, it carries out the next task in accordance with the current schedule.
Use random delay before starting the task	`Windows` `macOS` `Linux`	If the check box is selected, the task is not run strictly on schedule, but randomly within a certain interval, that is, the start times of the task are spread out. Randomized start times help avoid a great number of computers simultaneously accessing the Administration Server when the task is run on schedule. The range of randomized start times is automatically calculated when the task is created, depending on the number of computers that have the task assigned. Subsequently, the task is always run at its calculated start time. However, whenever task settings are modified or the task is run manually, the calculated start time changes. If the check box is cleared, the task is run exactly at scheduled time.
Stop task if it runs longer than (min)	`Windows` `Linux`	Limiting the task execution time After the specified amount of time, Kaspersky Endpoint Security stops the task. The task is not marked as completed. Next time Kaspersky Endpoint Security runs the task, it will be run from the beginning and on schedule.
