Timely updates of application databases ensure that your computer remains protected. File Anti-Virus, Web Anti-Virus and virus scan tasks use application databases to detect and neutralize malware on your computer. Application databases are updated regularly with new threats and ways to neutralize them, so it is important that you update the databases.
By default, Kaspersky Endpoint Security downloads application databases and new application modules from Kaspersky Lab update servers and installs them on your computer.
Start an application database update
Dedicated Kaspersky Lab update servers are the main source of updates for Kaspersky Endpoint Security. You can also use Kaspersky Security Center servers, local folders, or other web servers as an update source.
Select an update source
- Open the main application window.
- On the navigation panel in the upper pane of the main application window, click the
button.The application preferences window opens.
- Select the Update tab.
- In the Application section, click the Preferences button.
A window opens, in which you can select the update sources.
- On the Update sources tab, select the checkboxes next to the update sources that you want to use.
Note: By default, the list of update sources contains only Kaspersky Lab update servers and Kaspersky Security Center servers. When running an update, Kaspersky Endpoint Security refers to the list of update sources for the address of the first server and attempts to download the updates from this server. If the updates cannot be downloaded from the selected server, the application tries to connect and retrieve the updates from the next server. This continues until a connection is successfully established or all the available update servers have been tried. For subsequent updates the application first tries to access the server from which the most recent update was successfully made.
You can perform the following actions:
- Add a new update source to the list.
Click the
button and select the most suitable option from the dropdown list:
- To add a local or network folder as an update source, select Add folder. Select the required folder in the Finder window that opens.
- To add a web resource as an update source, select Add web address. In the window that opens, enter the server's web address in the Web address of update source field.
- Change the update source.
Select an update source in the list by double-clicking and make changes.
Note: Kaspersky Lab update servers and Kaspersky Security Center servers are update sources that cannot be edited or deleted.
- Temporarily disable retrieval of updates from the source.
Deselect the checkbox next to an update source that you want to disable. Kaspersky Endpoint Security will not be updated from this source until the checkbox is selected again.
- Delete an update source (available only for update sources added by the user).
Select the update source in the list and click the
button.
- Click the Save button to save the changes made to the update preferences.
Note: An Internet connection is required to download an update package from update servers. If you connect to the Internet via a proxy server, you may need to configure the network preferences.
Application database updates can be downloaded in one of the following modes:
- Automatically. Kaspersky Endpoint Security periodically checks for updates on Kaspersky Lab update servers. During a virus outbreak the frequency of these checks may increase and then decrease afterwards. If a set of the latest updates is stored on a server, Kaspersky Endpoint Security downloads them in the background and installs them on your computer. This is the default update mode.
- Manually. In this case, you start updates of Kaspersky Endpoint Security manually.
- By schedule. Kaspersky Endpoint Security is automatically updated according to a schedule.
By default, Kaspersky Endpoint Security module updates are downloaded and installed on the computer automatically.
Select the Kaspersky Endpoint Security update mode
- Open the main application window.
- On the navigation panel in the upper pane of the main application window, click the
button.
The application preferences window opens.
- Select the Update tab.
- In the Application databases section, select one of the options:
- If you want anti-virus databases and application modules to be automatically downloaded from Kaspersky Lab update servers and installed, select the Download updates automatically option.
- To start the application update process manually, select the Download updates manually option.
- If you want the application update to start automatically according to a schedule you specify, select the option corresponding to the update schedule.
Configure a Kaspersky Endpoint Security update schedule
- Open the main application window.
- On the navigation panel in the upper pane of the main application window, click the
button.
The application preferences window opens.
- Select the Update tab.
- In the Application databases section, select the option corresponding to a configured application update schedule.
- Click the Schedule button.
A window opens, in which you can configure the update schedule.
- Specify the application update frequency and time.
- Click the Save button to save changes made to the application update startup schedule.
During an update the application databases and modules are compared with those currently available at the update source. If the latest version of the databases is installed on your computer, the Update window or Protection Center display a message to inform you that the application databases are up-to-date. If the application version and application databases differ from those currently available from the update source, then only the missing update components are installed on your computer. Application databases are not copied in their entirety, which increases update speed and reduces Internet traffic.
Disable automatic download and installation of updates of application modules on the computer
- Open the main application window.
- On the navigation panel in the upper pane of the main application window, click the
button.
The application preferences window opens.
- Select the Update tab.
- In the Application section, deselect the Update application modules checkbox.
Note: If at the time of the update both application databases updates and application modules updates are available from the update source, Kaspersky Endpoint Security downloads the application module updates and installs them after the computer is restarted. The downloaded application module updates are not installed until the computer restarts. If the next application update becomes available on Kaspersky Lab servers before the computer is restarted and before the previously downloaded application module updates are installed, then Kaspersky Endpoint Security only updates the application databases.
If you connect to the Internet via a proxy server, you can configure the proxy server connection preferences. Kaspersky Endpoint Security uses these preferences to update application databases and download application module updates.

A window opens, in which you can configure the proxy server connection preferences.
- Configure the connection to a proxy server.
- Click the Save button to save the changes made to the proxy server connection preferences.
Before updating the application databases Kaspersky Endpoint Security creates backup copies of them so a rollback can be performed, if necessary. The rollback feature is useful if a new version of the application databases contains an incorrect signature that makes Kaspersky Endpoint Security block a safe application.
Note: If Kaspersky Endpoint Security databases become corrupted, you are advised to start an update to download and install the latest version of application databases.
Roll back the last update
- Open the main application window.
- On the navigation panel in the upper pane of the main application window, click the
button.

While updating Kaspersky Endpoint Security you can copy the downloaded updates to a local source. You can use a local copy of downloaded updates to update application databases and modules of Kaspersky Endpoint Security on other computers on the corporate network in order to reduce the amount of Internet traffic.
You can set up update distribution as follows:
- One of the computers on the network receives the Kaspersky Endpoint Security update package from Kaspersky Lab update servers or a different update source. The updates retrieved are placed in a shared folder.
Note: The shared folder must be created in advance.
- Other computers on the network refer to the shared folder as the update source.
