To perform scan tasks the application uses various combinations of settings. These groups of settings are called security levels. You can select one of the preset security levels or configure security level settings on your own. There are three security levels: High, Recommended, and Low. The Recommended security level is considered the optimal setting, and is recommended by Kaspersky.
To change a security level:
The task settings will appear in the right part of the window.
After you configure a custom security level, the name of the security level in the Security level section changes to Custom.
