Install Kaspersky Internet Security

If you already have Kaspersky Internet Security 2011 installed and need to activate, please read our Kaspersky 2011 Activation page.

Before you begin:

Please make sure you have removed your previous security software (including prior versions of Kaspersky) in the Control Panel before installing Kaspersky Internet Security 2011.

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 Internet Security 2011 CD, please skip to Step 2.

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

Step 1 - Save the Installation File:

You will be asked to Run, Save or Cancel the download. Click Save.

Click Save

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

Read the Kaspersky Security Network Data Collection Statement. This 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. Click Install.

At the end of this step, the Windows Firewall will be disabled. Kaspersky Internet Security 2011 includes a full-featured Firewall.

Step 3 - Configuration Wizard:

If you did not previously have Kaspersky, or your previous license expired, you will be prompted to activate a commercial 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 add the dashes. 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 Internet Security 2011.
