Enabling and disabling File Threat Protection

By default, the File Threat Protection component is enabled and runs in the mode recommended by Kaspersky experts. For File Threat Protection, Kaspersky Endpoint Security can apply different groups of settings. These groups of settings that are stored in the application are called security levels: High, Recommended, Low. The Recommended security level settings are considered to be the optimal settings recommended by Kaspersky experts (see the table below). You can select one of the preset security levels or manually configure security level settings. If you change the security level settings, you can always revert back to the recommended security level settings.

To enable or disable the File Threat Protection component:

1. In the main application window, click the button.
2. In the application settings window, select Essential Threat Protection → File Threat Protection.
3. Use the File Threat Protection toggle to enable or disable the component.
4. If you enabled the component, do one of the following in the Security level block:
   • If you want to apply one of the preset security levels, select it with the slider:
     • High. When this file security level is selected, the File Threat Protection component takes the strictest control of all files that are opened, saved, and started. The File Threat Protection component scans all file types on all hard drives, removable drives, and network drives of the computer. It also scans archives, installation packages, and embedded OLE objects.
     • Recommended. This file security level is recommended by Kaspersky Lab experts. The File Threat Protection component scans only the specified file formats on all hard drives, removable drives, and network drives of the computer, and embedded OLE objects. The File Threat Protection component does not scan archives or installation packages. The values of settings for the recommended security level are provided in the table below.
     • Low. The settings of this file security level ensure maximum scanning speed. The File Threat Protection component scans only files with specified extensions on all hard drives, removable drives, and network drives of the computer. The File Threat Protection component does not scan compound files.
   • If you want to configure a custom security level, click the Advanced Settings button and define your own component settings.

     You can restore the values of preset security levels by clicking the Restore recommended security level button.

5. Save your changes.

   File Threat Protection settings recommended by Kaspersky experts (recommended security level)

   Parameter	Value	Description
   File types	Files scanned by format	If this setting is enabled, the application scans infectable files only. Before scanning a file for malicious code, the internal header of the file is analyzed to determine the format of the file (for example, .txt, .doc, or .exe). The scan also looks for files with particular file extensions. A file which, due to its structure or format, can be used by intruders as a "container" to store and spread malicious code. As a rule, these are executable files, with such file extensions as .com, .exe, and .dll. There is a fairly high risk of intrusion of malicious code in such files.
   Heuristic Analysis	Light scan	The technology was developed for detecting threats that cannot be detected by using the current version of Kaspersky application databases. It detects files that may be infected with an unknown virus or a new variety of a known virus. When scanning files for malicious code, the heuristic analyzer executes instructions in the executable files. The number of instructions that are executed by the heuristic analyzer depends on the level that is specified for the heuristic analyzer. The heuristic analysis level ensures a balance between the thoroughness of searching for new threats, the load on the resources of the operating system, and the duration of heuristic analysis.
   Scan only new and modified files	On	Scans only new files and those files that have been modified since the last time they were scanned. This helps reduce the duration of a scan. This mode applies both to simple and to compound files.
   Use iSwift technology	On	This technology allows increasing scan speed by excluding certain files from scanning. Files are excluded from scanning by using a special algorithm that takes into account the release date of Kaspersky Endpoint Security databases, the date that the file was last scanned on, and any modifications to the scanning settings. The iSwift technology is an advancement of the iChecker technology for the NTFS file system.
   Use iChecker technology	On	This technology allows increasing scan speed by excluding certain files from scanning. Files are excluded from scans by using a special algorithm that takes into account the release date of Kaspersky Endpoint Security databases, the date when the file was last scanned, and any modifications to the scan settings. There are limitations to iChecker Technology: it does not work with large files and applies only to files with a structure that the application recognizes (for example, EXE, DLL, LNK, TTF, INF, SYS, COM, CHM, ZIP, and RAR).
   Scan files in Microsoft Office formats	On	Scans Microsoft Office files (DOC, DOCX, XLS, PPT and other Microsoft extensions). Office format files include OLE objects as well. Kaspersky Endpoint Security scans office format files that are smaller than 1 MB, regardless of whether the check box is selected or not.
   Scan mode	Smart mode	In this mode, File Threat Protection scans an object based on an analysis of actions taken on the object. For example, when working with a Microsoft Office document, Kaspersky Endpoint Security scans the file when it is first opened and last closed. Intermediate operations that overwrite the file do not cause it to be scanned.
   Action on threat detection	Disinfect, delete if disinfection fails	If this option is selected, the application automatically attempts to disinfect all infected files that are detected. If disinfection fails, the application deletes the files.
