If you already have Kaspersky Internet Security 2015 installed and need to activate it, please read our Activation page.

Before you begin:

  • Please make sure you have removed your previous security software from the Control Panel before installing the application.
  • If you need help removing the previously installed security programs, please check our list of removal tools for conflicting software.
  • If you have a previous version of Kaspersky installed on your PC, you can simply install the new version on top of it.

Step 1. Save the Installation File

Click the below button to begin the download. (If you have Dial-Up Internet, we suggest you wait for the Backup CD to arrive to install.)

The web browser will then ask you where to save the file. Use the drop-down menu to select your Desktop, then click Save. Download speeds will vary depending on your Internet connection, but could take from a few minutes to an hour.

When the download completes, click Run.

Step 2. Run the Setup Wizard

You will briefly see the install process copy the installation files to your computer.

The install process will check if there is a newer version online and prompt you to download it if needed.

The Setup Wizard will open, click Install.

The Kaspersky Security Network allows us to detect and collect new viruses based on their behavior as well as non-personal data about how you use our software. The Kaspersky Security Network does not collect or process any personal information.

At the end of this step, the Windows Firewall will be disabled. Kaspersky Internet Security 2015 includes a full-featured Firewall.

You may see a notification from the Windows Security Center that there are problems while the application is still being installed. This is normal and will automatically resolve itself after the process completes.

The wizard will then check the built-into-Windows programs and set levels for each in the Application Control feature.

Once the Setup Wizard completes, you will receive a notification that the installation has completed successfully. Please click Finish.

If you did not previously have Kaspersky Internet Security, or your previous license expired, you will be prompted to activate a commercial (retail) license. Enter your 20-character activation code, which is four sets of five characters, or XXXXX-XXXXX-XXXXX-XXXXX. The wizard will automatically capitalize letters and move to the next box. Click Activate.

Your activation code can be found on your order email, the back of the CD sleeve, or the Activation Card that is included in the DVD case.

If you are not asked to activate, the wizard has detected your existing valid license. Should you need to activate after the install completes, follow these steps to activate Kaspersky Internet Security 2015.

Please wait while the wizard activates the program. You will receive a notification that the product was activated successfully. Please click Finish to begin using Kaspersky Internet Security 2015.


The program will begin a database update automatically after several minutes, or you can start an update now. We recommend doing a Full Scan of your system after the update completes.

If you are new to Kaspersky Lab products, we use a color coded dashboard to show the protection status of your computer:

  • Green — The computer is protected.
  • Yellow — Warning of minor issue.
  • Red — The computer is at risk.
