If you are a renewal customer and wish to continue using the prior version, you can reactivate, but we recommend installing the latest version of Kaspersky Small Office Security 3.0 for the best experience.

If you have enjoyed your trial, or your existing Kaspersky Small Office Security 3.0 install needs to be reactivated, you do not need to remove and reinstall the software. Just enter the new Activation Code from your order email.

The Kaspersky trial is the same software as the licensed version, except the trial lasts only 30 days. All functionality is the same.

Activate Kaspersky Small Office Security 3.0

Locate your activation code. This can be found in your order email from our online Store. The code will be four sets of five characters and looks like XXXXX-XXXXX-XXXXX-XXXXX.

Open Kaspersky and click on Enter activation code on the lower right.

Click on the Activate the Application button.

Enter your 20 character activation code, and then Click Next.

Please wait while the wizard connects to our Activation Server and activates your Kaspersky license. After the license is installed, click Finish.
