Kaspersky Free is a limited free version of Kaspersky. Using the free version of the application gives you high-quality protection supplemented by advanced features and a user interface fully reworked for ease of use.

You can activate the application by logging into your My Kaspersky account from the device on which you are installing the application. Kaspersky Free does not work if your device is not connected to your account. You can create an account in the account connection window during application activation or on My Kaspersky website. You can also use credentials from other Kaspersky resources to sign in to your account.

The Kaspersky Free subscription is renewed without your intervention.

Moreover, you can always switch to a paid Kaspersky subscription without downloading and installing any additional software.

What is included in Kaspersky Free?

File Anti-Virus

File Anti-Virus prevents infection of the computer's file system. The component starts upon startup of the operating system, continuously remains in the computer's RAM, and scans all files that are opened, saved, or launched on your computer and all connected drives. Kaspersky Free intercepts each attempt to access a file and scans the file for known viruses and other malware. Further access to the file is allowed only if the file is not infected or is successfully disinfected. If a file cannot be disinfected for any reason, it is deleted. A copy of the file is moved to Quarantine when that happens. If an infected file is placed in the same location where the deleted file with the same name used to be, Quarantine saves only a copy of the last file. A copy of the previous file with the same name is not saved.

Mail Anti-Virus

Mail Anti-Virus scans incoming and outgoing email messages on your computer. An email message is available to the recipient only if it does not contain dangerous objects.

Safe Browsing

Safe Browsing intercepts and blocks the execution of scripts on websites if they pose a threat. Safe Browsing also monitors all web traffic and blocks access to dangerous websites.


Anti-Phishing allows checking URLs to find out if they are included in the list of phishing URLs. This component is built into Safe Browsing.

System Watcher

The System Watcher component rolls back the changes made to the operating system by malicious or other activity of applications.

The component protects against malware, including:

  • Exploits
  • Screen lockers
  • Encryptors that encrypt data
  • Ransomware that encrypts data or blocks access to files or the system and extorts ransom for restoring the files or access to them

Disabling this component is not recommended.

Network Attack Blocker

Network Attack Blocker loads at operating system startup and tracks incoming network traffic for activities characteristic of network attacks. When an attempt to attack your computer is detected, Kaspersky Free blocks all network activity from the attacking computer that is aimed at your computer.

On-Screen Keyboard

On-Screen Keyboard prevents interception of data entered on the hardware keyboard and protects personal data against interception attempts that use screen shots.

Antimalware Scan Interface (AMSI)

Antimalware Scan Interface (AMSI) allows a third-party application that supports AMSI to send objects (for example, PowerShell scripts) to Kaspersky for additional scanning and to receive scan results for these objects.
