Switch to new Kaspersky Security Cloud Free

In the nearest future we are going to replace Kaspersky Free with a more advanced solution — Kaspersky Security Cloud Free.

In some time we will gradually start discontinuing the support of Kaspersky Free: we will stop releasing antivirus database updates, therefore protection against latest threats will no longer be guaranteed. Kaspersky Security Cloud Free is already available and we encourage you to switch to it as soon as possible. It includes all the same features, as well as new ones: protection for mobile devices (Android and iOS), secure connection to public Wi-Fi networks (up to 300 MB per day), password management, checking accounts for possible data leaks, and personalized recommendations on protection settings.

Also, you can try our solutions: Kaspersky Anti-Virus, Kaspersky Internet Security, Kaspersky Total Security or Kaspersky Security Cloud.
