Custom Scan task (Scan_File, ID:3)

The Custom Scan task is used to store the setting values that are applied by executing the kesl-control --scan-file command.

When running the command, the [ScanScope.item_#] and [ExcludedFromScanScope.item_#] sections in the settings of this task are not inherited from the original task with ID=3.

You can change scan settings for the Scan_File task from the command line.

Upon detecting malware, Kaspersky Endpoint Security may remove the infected file and terminate the malware process started from this file.

The table describes all available values and the default values of all the settings that you can specify for the Custom Scan task.

Custom Scan task settings

Setting

Description

Values

ScanFiles

Enables file scan.

Yes (default value) — Scan files.

No — Do not scan files.

ScanBootSectors

Enables boot sector scans.

Yes — Scan boot sectors.

No (default value) — Do not scan boot sectors.

ScanComputerMemory

Enables process memory and kernel memory scans.

Yes — Scan process memory and kernel memory.

ScanStartupObjects

Enables startup object scans.

Yes — Scan startup objects.

No (default value) — Do not scan startup objects.

ScanArchived

Enables scanning of archives (including SFX self-extracting archives).

The application scans the following archives: .zip; .7z*; .7-z; .rar; .iso; .cab; .jar; .bz; .bz2; .tbz; .tbz2; .gz; .tgz; .arj. The list of supported archive formats depends on the application databases being used.

Yes (default value) — Scan archives. If the FirstAction=Recommended value is specified, then, depending on the archive type, the application deletes either the infected object or the entire archive that contains the threat.

No — Do not scan archives.

ScanSfxArchived

Enables scanning of self-extracting archives only (archives that contain an executable extraction module).

Yes (default value) — Scan self-extracting archives.

No — Do not scan self-extracting archives.

ScanMailBases

Enables scanning email databases of Microsoft Outlook, Outlook Express, The Bat!, and other mail clients.

Yes — Scan files of email databases.

No (default value) — Do not scan files of email databases.

ScanPlainMail

Enables scanning of plain text email messages.

Yes — Scan plain text email messages.

No (default value) — Do not scan plain text email messages.

SizeLimit

Maximum size of an object to be scanned (in megabytes). If the object to be scanned is larger than the specified value, the application skips this object.

0 – 999999

0 — The application scans objects of any size.

Default value: 0.

TimeLimit

Maximum object scan duration (in seconds). The application stops scanning the object if it takes longer than the time specified by this setting.

0 – 9999

0 — The object scan time is unlimited.

Default value: 0.

FirstAction

Selection of the first action to be performed by the application on the infected objects.

Disinfect — The application tries to disinfect an object and save a copy of it to the Storage. If disinfection fails (for example, if the type of object or the type of threat in the object cannot be disinfected), then the application leaves the object unchanged. If the first action is Disinfect, it is recommended to specify a second action using the SecondAction setting.

Remove — The application removes the infected object after creating a backup copy of it.

Recommended (perform recommended action) — The application automatically selects and performs an action on the object based on information about the threat detected in the object. For example, Kaspersky Endpoint Security immediately removes Trojans since they do not incorporate themselves into other files and therefore they do not need to be disinfected.

Skip — The application does not try to disinfect or delete infected objects. Information about the infected object is logged.

Default value: Recommended.

SecondAction

Selection of the second action to be performed by the application on the infected objects. The application performs the second action if the first action fails.

The possible values of the SecondAction setting are the same as those of the FirstAction setting.

If Skip or Remove is selected as the first action, the second action does not need to be specified. It is recommended to specify two actions in all other cases. If you have not specified the second action, the application applies Skip as the second action.

Default value: Skip.

UseExcludeMasks

Enables scan exclusions for the objects specified by the ExcludeMasks.item_# setting.

Yes — Exclude objects specified by the ExcludeMasks.item_# setting from scans.

No (default value) — Do not exclude objects specified by the ExcludeMasks.item_# setting from scans.

ExcludeMasks.item_#

Excludes objects from being scanned by name or mask. You can use this setting to exclude an individual file from the specified scan scope by name or exclude several files at once using masks in the shell format.

The default value is not defined.

Example:

UseExcludeMasks=Yes

ExcludeMasks.item_0000=eicar1.*

ExcludeMasks.item_0001=eicar2.*

UseExcludeThreats

Enables scan exclusions for objects containing the threats specified by the ExcludeThreats.item_# setting.

Yes — Exclude objects containing the threats specified by the ExcludeThreats.item_# setting from scans.

No (default value) — Do not exclude objects containing the threats specified by the ExcludeThreats.item_# setting from scans.

ExcludeThreats.item_#

Excludes objects from scans by the name of the threats detected in them. Before specifying a value for this setting, make sure that the UseExcludeThreats setting is enabled.

In order to exclude an object from scans, specify the full name of the threat detected in this object – the string containing the application's decision that the object is infected.

For example, you may be using a utility to collect information about your network. To keep the application from blocking it, add the full name of the threat contained in it to the list of threats excluded from scans.

You can find the full name of the threat detected in an object in the application log or on the website https://threats.kaspersky.com.

The setting value is case-sensitive.

The default value is not defined.

Example:

UseExcludeThreats=Yes

ExcludeThreats.item_0000=EICAR-Test-*

ExcludeThreats.item_0001=?rojan.Linux

ReportCleanObjects

Enables logging of information about scanned objects that the application reports as not being infected.

You can enable this setting, for example, to make sure that a particular object was scanned by the application.

Yes — Log information about non-infected objects.

No (default value) — Do not log information about non-infected objects.

ReportPackedObjects

Enables logging of information about scanned objects that are part of compound objects.

You can enable this setting, for example, to make sure that an object within an archive has been scanned by the application.

Yes — Log information about scanned objects within archives.

No (default value) — Do not log information about scanned objects within archives.

ReportUnprocessedObjects

Enables logging of information about objects that have not been processed for some reason.

Yes — Log information about unprocessed objects.

No (default value) — Do not log information about unprocessed objects.

UseAnalyzer

Enables heuristic analysis.

Heuristic analysis helps the application to detect threats even before they become known to virus analysts.

Yes (default value) — Enable Heuristic Analyzer.

No — Disable Heuristic Analyzer.

HeuristicLevel

Specifies the heuristic analysis level.

You can specify the heuristic analysis level. The heuristic analysis level sets the balance between the thoroughness of searches for threats, the load on the operating system's resources, and the scan duration. The higher the heuristic analysis level, the more resources and time are required for scanning.

Light — The least thorough scan with minimum load on the system.

Medium — A medium heuristic analysis level with a balanced load on the system.

Deep — The most thorough scan with maximum load on the system.

Recommended (default value) — The recommended value.

UseIChecker

Enables usage of the iChecker technology.

If Kaspersky Endpoint Security is used in Light Agent mode to protect virtual environments, the use of the iChecker technology is not supported. Scan optimization is implemented by means of the Protection Server.

Yes (default value) — Enable use of the iChecker technology.

No — Disable use of the iChecker technology.

DeviceNameMasks.item_#

List of device names. The application will scan boot sectors of these devices.

The setting value cannot be empty. At least one device name mask must be specified to run this task.

AllObjects – scan boot sectors of all devices.

<device name mask> – Scan boot sectors of the devices whose names match the specified mask.

Default value: /** – any set of characters in the device name, including the / character.

The [ScanScope.item_#] section contains the following settings:

AreaDesc

Description of the scan scope, which contains additional information about the scan scope. The maximum length of the string specified using this setting is 4096 characters.

Default value: All objects.

Example:

AreaDesc="Scanning of email databases"

UseScanArea

Enables scans of the specified scope. To run the task, enable scans of at least one scope.

Yes (default value) — Scan the specified scope.

No — Do not scan the specified scope.

AreaMask.item_#

Scan scope limitation. Within the scan scope, the application scans only the files that are specified using the masks in the shell format.

If this setting is not specified, the application scans all the objects in the scan scope. You can specify several values for this setting.

The default value is * (scan all objects).

Example:

AreaMask.item_<item number>=*doc

Path

Path to the directory with objects to be scanned.

<path to local directory> — Scan objects in the specified directory.

Shared:NFS — Scan the device file system resources that are accessible via the NFS protocol.

Shared:SMB – Scan the device file system resources that are accessible via the Samba protocol.

Mounted:NFS – Scan the remote directories mounted on a device using the NFS protocol.

Mounted:SMB – Scan the remote directories mounted on a device using the Samba protocol.

AllRemoteMounted – Scan all remote directories mounted on the device using the Samba and NFS protocols.

AllShared – Scan all the device file system resources that are accessible via the Samba and NFS protocols.

<file system type> — Scan all the resources of the specified device file system.

The [ExcludedFromScanScope.item_#] section contains the following settings:

AreaDesc

Description of the scan exclusion scope, which contains additional information about the exclusion scope.

The default value is not defined.

UseScanArea

Excludes the specified scope from scans.

Yes (default value) — Exclude the specified scope.

No — Do not exclude the specified scope.

AreaMask.item_#

Limitation of scan exclusion scope. In the exclusion scope, the application excludes only the files that are specified using masks in the shell format.

If this setting is not specified, the application excludes all the objects in the exclusion scope. You can specify several values for this setting.

Default value: * (exclude all objects).

Path

Path to the directory with objects to be excluded.

<path to local directory> — Exclude objects in the specified directory (including subdirectories) from scans. You can use masks to specify the path.

In order to optimize the operation of scan tasks, it is recommended to add the path with snapshots mounted by the system in the read-only mode to the exclusions for the systems with the btrfs file system and enabled active snapshots. For example, for the systems based on SUSE/OpenSUSE, you can add the following exclusion /.snapshots/*/snapshot/.

Mounted:NFS– Exclude the remote directories mounted on a device using the NFS protocol from scan.

Mounted:SMB – Exclude the remote directories mounted on a device using the Samba protocol from scan.

AllRemoteMounted – Exclude all remote directories mounted on the device using the Samba and NFS protocols from scan.

<file system type> — Exclude all the resources of the specified device file system from scans.

Remote directories are excluded from scans by the application only if they were mounted before the task was started. Remote directories mounted after the task is started are not excluded from scans.
