If you already have Kaspersky PURE 3.0 installed and need to activate, please read our Kaspersky PURE 3.0 Activation page.
Please make sure you have removed your previous security software (including prior versions of Kaspersky) in the Control Panel before installing Kaspersky PURE 3.0.
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 PURE 3.0 CD, please skip to Step 2.
If you have purchased online, follow Step 1 to download your software.
If you have Dial-Up Internet, we suggest you wait for the Backup CD to arrive to install.
Click the below button to begin the download.
You will be asked to Run, Save or Cancel the download. 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.
When the download completes, click Run.
Close all open windows except this web page.
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. Read the End User License Agreement and click Install.
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 PURE 3.0 includes a full-featured Firewall.
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.
The first time Kaspersky PURE 3.0 starts, it will add most Windows programs to the database, allowing known programs access through the PURE Firewall. Additional programs will be added the first time you use them.
The wizard will then check the Windows files and set levels for each application for the Application Control feature.
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 PURE 3.0.
Please wait while the wizard activates your Kaspersky PURE 3.0.
Click Finish to begin using Kaspersky PURE 3.0. The first update will begin automatically.
