Proxy server settings

This switch enables / disables the use of a proxy server for Internet connections. An Internet connection is required for the operation of some protection components in Kaspersky, as well as for updating databases and application modules.

Kaspersky detects the proxy server settings automatically using WPAD (Web Proxy Auto-Discovery Protocol).

If this protocol cannot determine the address, Kaspersky uses the proxy server settings specified in the Chromium-based Microsoft Edge browser. Kaspersky does not take into account the settings of proxy servers defined for other browsers that are installed on the user's computer.

Kaspersky uses a proxy server that differs from the one specified in the browser connection settings.

The field is available if the Use specified proxy server settings setting is selected.

Authentication is verification of the user's sign-in information.

This check box enables / disables the use of authentication on the proxy server.

If this check box is selected, Kaspersky will first attempt to perform NTLM authentication, and then BASIC authentication.

If this check box is cleared, or if the proxy server settings are not defined, Kaspersky will attempt to perform NTLM authentication using the account under which the task (for example, an update task) has been run.

If the proxy server requires authentication and no user name and password were entered, or if the specified data was not accepted by the proxy server, a window opens, prompting you for the user name and password. If authentication is successful, Kaspersky uses the specified user name and password in the future. Otherwise, Kaspersky will prompt you for the authentication settings again.

The user name used for authentication on the proxy server.

The password for the specified user name.

If this check box is selected, Kaspersky does not use a proxy server when updating databases and application modules from a local or network folder.

If this check box is cleared, Kaspersky uses the proxy server when updating databases and application software modules from a local or network folder.
