Critical Areas Scan task settings

Setting	Description
Task priority	In this group of settings you can select the task priority: Low— the scan task is executed with a low priority: no more than 10% of processor resource consumption. Execution of the task takes more time, but the application allocates resources for other tasks. Normal (default value) — the scan task is executed with a normal priority: no more than 50% of all processor resources. High — the scan task is executed with a high priority, without limiting the consumption of processor resources. Specify this value to perform the current scan task faster.
Scan archives	This check box enables or disables scan of archives. If the check box is selected, the application scans the archives. To scan an archive, the application has to unpack it first, which may slow down scanning. You can reduce the archive scan time by configuring the Skip object if scan takes longer than (sec) and Skip objects larger than (MB) settings in the General scan settings section. If the check box is cleared, the application does not scan the archives. The check box is selected by default.
Scan SFX archives	This check box enables or disables self-extracting archive scans. Self-extracting archives are the archives that contain an executable extraction module. If the check box is selected, the application scans self-extracting archives. If the check box is cleared, the application does not scan self-extracting archives. This check box is available if the Scan archives check box is unchecked. The check box is selected by default.
Scan mail databases	This check box enables or disables scans of mail databases of Microsoft Outlook, Outlook Express, The Bat!, and other mail applications. If the check box is selected, the application scans mail database files. If the check box is cleared, the application does not scan mail database files. This check box is cleared by default.
Scan mail format files	This check box enables or disables scan of files of plain-text email messages. If this check box is selected, the application scans plain-text messages. If this check box is cleared, the application does not scan plain-text messages. This check box is cleared by default.
Skip object if scan takes longer than (sec)	A field for specifying the maximum time to scan an object, in seconds. After the specified time, the application stops scanning the object. Available values: 0–9999. If the value is set to 0, the scan time is unlimited. Default value: 0.
Skip objects larger than (MB)	The field for specifying the maximum size of an archive to scan, in megabytes. Available values: 0–999999. If the value is set to 0, the application scans objects of any size. Default value: 0.
Log clean objects	This check box enables or disables the logging of ObjectProcessed type events. If this check box is selected, the application logs events of the ObjectProcessed type for all scanned objects. If this check box is cleared, the application does not log events of the ObjectProcessed type for any scanned object. This check box is cleared by default.
Notify about unprocessed files	This check box enables or disables the logging ObjectNotProcessed type events if a file cannot be processed during a scan. If this check box is selected, the application logs the events of the ObjectNotProcessed type. If this check box is cleared, the application does not log the events of the ObjectNotProcessed type. This check box is cleared by default.
Log packed objects	This check box enables or disables the logging of PackedObjectDetected type events for all packed objects that are detected. If this check box is selected, the application logs the events of the PackedObjectDetected type. If this check box is cleared, the application does not log the events of the PackedObjectDetected type. This check box is cleared by default.
Use iChecker technology	This check box enables or disables scan of only new and modified since the last scan files. If the check box is selected, the application scans only new files or the files modified since the last scan. If the check box is cleared, the application scans the files regardless of the creation or modification date. The check box is selected by default.
Use heuristic analysis	This check box enables or disables heuristic analysis during file scans. The check box is selected by default.
Heuristic analysis level	If the Use heuristic analysis check box is selected, you can select the heuristic analysis level in the drop-down list: Light is the least detailed scan with minimal system load. Medium is a medium scan with balanced system load. Deep is the most detailed scan with maximum system load. Recommended (default value) is the optimal level recommended by Kaspersky experts. It ensures an optimal combination of protection quality and impact on the performance of the protected devices.
First action	In this drop-down list, you can select the first action to be performed by the application on an infected object that has been detected: Disinfect the object. A copy of the infected object will be saved in the Storage. Remove the object. A copy of the infected object will be saved in the Storage. Perform recommended action on the object, based on data about the danger level of the threat detected in the file and about the possibility of disinfecting it (default value). Skip the object.
Second action	In this drop-down list, you can select the second action to be performed by the application on an infected object, in case the first action is unsuccessful: Disinfect the object. A copy of the infected object will be saved in the Storage. Remove the object. A copy of the infected object will be saved in the Storage. Perform recommended action on the object, based on data about the danger level of the threat detected in the file and about the possibility of disinfecting it. Skip the object (default value).
Scan scopes	The table that contains the scopes scanned by the task. By default, the table contains one scan scope that includes all directories of the local file system. You can add, configure, delete, move up, or move down scan scopes in the table. Clicking the Move down button moves the selected item down in the table. Kaspersky Embedded Systems Security scans objects in the specified scopes in the order they are listed in the table of scan scopes. If you want to configure security settings for a subdirectory that are different from the security settings of the parent directory, you must place the subdirectory higher than its parent directory in the table. This button is available if a scope is selected in the table. Clicking the Move up button moves the selected item up in the table. Kaspersky Embedded Systems Security scans objects in the specified scopes in the order they are listed in the table of scan scopes. If you want to configure security settings for a subdirectory that are different from the security settings of the parent directory, you must place the subdirectory higher than its parent directory in the table. This button is available if a scope is selected in the table. Clicking the Delete button excludes the selected scope from scans. This button is available if at least one scan scope is selected in the table. Clicking the scan scope name opens the <Scan scope name> window. In this window, you can modify the settings of the selected scan scope. Clicking the Add button opens the <New scan scope> window. In this window, you can define a new scan scope.

Add scan scope window

In this window, you can add and configure scan scopes.

Scan scope settings

Setting	Description
Scan scope name	Field for entering the scan scope name. This name will be displayed in the table in the Scan scopes window. The entry field must not be blank.
Use this scope	This check box enables or disables scans of this scope by the application. If this check box is selected, the application processes this scan scope. If this check box is cleared, the application does not process this scan scope. You can later include this scope in the component settings by selecting the check box. The check box is selected by default.
File system, access protocol and path	You can select the type of file system in the drop-down list: Local (default value) – local directories. If this item is selected, you need to indicate the path to the local directory. Mounted – Mounted remote or local directories. If this item is selected, you need to indicate the protocol or name of the file system. Shared — The protected server's file system resources accessible via the Samba or NFS protocol. All remote mounted – all remote directories mounted on the device using the Samba and NFS protocols. All shared — All of the protected server's file system resources accessible via the Samba and NFS protocols.
Access protocol	You can select the remote access protocol in the drop-down list: NFS: remote directories mounted on a device using the NFS protocol. Samba: remote directories mounted on a device using the Samba protocol. Custom – resources of the device's file system specified in the field below. This drop-down list is available if the Shared or Mounted type is selected in the drop-down list of file systems.
Path	This is the entry field for specifying the path to the directory that you want to include in the scan scope. You can use masks to specify the path. You can use the `` (asterisk) character to create a file or directory name mask. You can indicate a single `` character to represent any set of characters (including an empty set) preceding the `/` character in the file or directory name. For example, `/dir//file` or `/dir///file`. You can indicate two consecutive `` characters to represent any set of characters (including an empty set and the `/` character) in the file or directory name. For example, `/dir/*/file/` or `/dir/file/`. The `` mask can be used only once in a directory name. For example, `/dir///file` is an incorrect mask. You can use a single `?` character to represent any one character in the file or directory name. The / path is specified by default – the application scans all directories of the local file system. This field is available if the Local type is selected in the drop-down list of file systems. If the Local type is selected in the drop-down list of file systems, and the path is not specified, the application scans all directories of the local file system.
Name of shared resource	The field for entering the name of the file system shared resource, where the directories that you want to add to the scan scope are located. The field is available if the Mounted type is selected in the File system drop-down list and the Custom item is selected in the Access protocol drop-down list.
Masks	The list contains name masks for the objects that the application scans. By default the list contains the * mask (all objects). You can add, edit, or delete masks. Clicking the Delete button removes the selected item from the table. This button is available if at least one item is selected in the table. The selected element's settings are changed in a separate window. Clicking the Add button opens a window where you can specify the new item settings.
