Anti-Virus Installation Help

If you already have Kaspersky Anti-Virus 2013 installed and need to activate, please read our Kaspersky Anti-Virus 2013 Activation page.

Before you begin:

Please make sure you have removed your previous anti-virus software (including prior versions of Kaspersky) in the Control Panel before installing Kaspersky Anti-Virus 2013.

If you need help removing the previously installed security programs, please check our list of removal tools for conflicting software.

If you are installing using the Kaspersky Anti-Virus 2013 CD, please skip to Step 2.

If you have purchased online, follow Step 1 to download your software.

Step 1 - Save the Installation File:

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 Close.

Close all open windows except this web page, then locate the file on your Desktop and double-click on it to begin the installation process.

If prompted to run the file, click Run.

Step 2 - Install Process:

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.

Click on the Activate the application button.

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.

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

Step 3 - Configuration Wizard:

If you did not previously have Kaspersky, 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 Next.

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 Anti-Virus 2013.

Please wait while the wizard activates the program. Click Finish to begin using Kaspersky Anti-Virus 2013.


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, we use a color coded dashboard to show the security status of your computer. Click on the computer screen icon to see more details.

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

You can learn more about the program’s settings in our Kaspersky Anti-Virus 2013 Knowledge Base.
