Kaspersky Free

Kaspersky Protection browser extension

In order for Kaspersky Free to fully support browsers, the Kaspersky Protection extension must be installed and enabled in the browsers. Kaspersky Free uses the Kaspersky Protection extension to inject a script into traffic. The application uses this script to interact with the web page. The application protects data transmitted by the script using a digital signature. The application can embed the script without using the Kaspersky Protection extension.

The application signs data transmitted by the script using the installed anti-virus databases and requests to Kaspersky Security Network. The application sends requests to Kaspersky Security Network regardless of whether or not you accepted the terms of the Kaspersky Security Network Statement.

When working with your browser, the Kaspersky Protection extension allows you to:

Inform about website problem
