About the key file

A key file is a file with the .key extension that you receive from Kaspersky Lab. Key files are designed to activate the application by adding a key.

You receive a key file at the email address that you provided when you bought Kaspersky Anti-Virus or ordered the trial version of Kaspersky Anti-Virus.

You do not need to connect to Kaspersky Lab activation servers in order to activate the application with a key file.

You can restore a key file if it has been accidentally deleted. You may need a key file to register a Kaspersky CompanyAccount, for example.

To recover a key file, you must do one of the following:

• Contact Technical Support.
• Obtain a key file on the Kaspersky Lab website using your existing activation code.
