For detailed information about activation codes and licenses, see this article.
The trial license allows access to all application features, but its term is limited to one month. You can use the trial license to evaluate the application.
After the trial license key expires, database update will become unavailable.
You can download a trial version from the Kaspersky Lab official website.
If you have Kaspersky Internet Security 2018 installed, you can still activate a trial version of Kaspersky Anti-Virus 2018. If you would like to continue using the product after the trial license expires, buy a commercial license.
To activate the trial version:
Each copy of a multiple-device license for Kaspersky Anti-Virus 2018 (for example, a 3 PCs license) is installed and activated in the same way on all computers you want to protect.
To activate Kaspersky Internet Security 2018 on all computers, use one and the same activation code you purchased.
You can find instructions on how to solve issues in the General articles: Activation errors section.
If the issue persists, send a request to Kaspersky Lab Technical Support via the My Kaspersky service. In your request, give a detailed description of the problem. For more information about My Kaspersky, see the Online Help page.
