To protect the computer's file system, the File Threat Protection component applies various groups of settings. These groups of settings are called security levels. There are three preset security levels: High, Recommended, and Low. The Recommended security level settings are considered to be the optimal settings recommended by Kaspersky experts.
To change a security level:
The settings of the File Threat Protection component are displayed 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.
