In order for Kaspersky Anti-Virus to fully support browsers, the Kaspersky Protection extension has to be installed and enabled in browsers. Kaspersky Anti-Virus 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. Kaspersky Anti-Virus can embed the script without using the Kaspersky Protection extension.
Kaspersky Anti-Virus 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.
Installing the Kaspersky Protection extension in Chromium-based Microsoft Edge, Mozilla Firefox, and Google Chrome
The Kaspersky Protection extension is not automatically installed in Chromium-based Microsoft Edge, Mozilla Firefox, and Google Chrome. If the Kaspersky Protection extension is not installed in the browser, the application prompts you to go to the extensions download page and manually install Kaspersky Protection when the browser is started.
Yandex Browser support
When using Yandex Browser, the following application components are operating:
- URL Advisor
- Web Anti-Virus
- Anti-Phishing
Internet Explorer support
Starting with Kaspersky Anti-Virus 2021, the Kaspersky Protection extension will no longer support the browser Internet Explorer. If you want to continue using the Kaspersky Protection extension in Internet Explorer, you can go back to the previous version of the application.
