To operate the application, you must purchase a license for application use.
The license has a limited term. License expiration may be followed by a grace period during which you may use all
application features without limitations.
If you have not renewed your license (see the section "Renewing a license" on page 38), the application may switch to
limited protection mode (see the section "About limited functionality mode" on page 32) when the grace period expires.
Some application features are unavailable in limited protection mode. The duration of limited protection mode depends
on your region and licensing terms. When limited protection mode expires, all application features become unavailable.
You may find information about the grace period and limited functionality mode in the Licensing window, which opens
by clicking the License link in the lower part of the main window.
We recommend renewing the license before it expires, in order to ensure maximum protection of your computer against
all security threats.
Before purchasing a license, you can get a free trial version of Kaspersky Internet Security. The trial version of
Kaspersky Internet Security remains functional during a short evaluation period. After the evaluation period expires, all
the features of Kaspersky Internet Security are disabled. To continue using the application, you must purchase a license.
If you do not wish to renew protection of your computer, you can remove Kaspersky Internet Security (see the section
"Removing the application" on page 29).
