General application settings

General application settings define the operation of the application as a whole and the operation of individual functions.

Setting	Description	Values
`SambaConfigPath`	Directory that stores the Samba configuration file. The Samba configuration file is required to ensure that the `AllShared` or `Shared:SMB` values can be used for the `Path` setting.	The standard directory of the SAMBA configuration file on the computer is specified by default. Default value: /etc/samba/smb.conf. The application must be restarted after this setting is changed.
`NfsExportPath`	The directory where the NFS configuration file is stored. The NFS configuration file is required to ensure that the `AllShared` or `Shared:NFS` values can be used for the `Path` setting.	The standard directory of the NFS configuration file on the computer is specified by default. Default value: /etc/exports. The application must be restarted after this setting is changed.
`TraceLevel`	Enable application tracing and the level of detail in the trace files.	`Detailed` – Generate a detailed trace file. `MediumDetailed` – Generate a trace file that contains informational messages and error messages. `NotDetailed` – Generate a trace file that contains error messages. `None` (default value) — Do not generate a trace file.
`TraceFolder`	The directory that stores the application trace files.	Default value: /var/log/kaspersky/kfl. If you specify a different directory, make sure that the user under which the Kaspersky application is running has read/write permissions for this directory. Root privileges are required to access the default trace files directory. The application must be restarted after this setting is changed.
`TraceMaxFileCount`	Maximum number of application trace files.	1–10000 Default value: 10. The application must be restarted after this setting is changed.
`TraceMaxFileSize`	Specifies the maximum size of an application trace file (in megabytes).	1–1000 Default value: 500. The application must be restarted after this setting is changed.
`BlockFilesGreaterMaxFileNamePath`	Blocks access to files for which the full path length exceeds the defined settings value specified in bytes. If the length of the full path to the scanned file exceeds the value of this setting, scan tasks skip this file during scanning. This setting is not available for operating systems that use the fanotify technology.	4096–33554432 Default value: 16384. After changing the value of this setting, the File Threat Protection task needs to be restarted.
`DetectOtherObjects`	Enable detection of legitimate applications that intruders can use to compromise devices or data.	`Yes`: enable detection of legitimate applications that intruders can use to compromise devices or data. `No` (default): disable detection of legitimate applications that intruders can use to compromise devices or data.
`FileBlockDuringScan`	Enabling the file operation intercept mode with blocking access to files for the duration of the scan. The file operation interception mode affects the operation of the File Threat Protection component.	`Yes` (default value) to block access to files for the duration of the scan. `No` to allow access to files during the scan. Requests to any file is allowed, scanning is done asynchronously. This file operation interception mode has less impact on the system performance, but there is a risk that a threat in a file will not be disinfected or deleted if the file can, for example, change its name during a scan before the application makes a decision on the status of the file.
`UseKSN`	Enabling Kaspersky Security Network usage:	`Yes` (default value) – accept the terms of the Kaspersky Security Network Statement and enable the use of KSN. `No` – do not accept the terms of the Kaspersky Security Network Statement and disable the use of KSN.
`UseProxy`	Enables use of a proxy server by components of the Kaspersky application. A proxy server can be used to communicate with Kaspersky Security Network, to activate the application, and when updating application databases and modules.	`Yes` - enable the use of a proxy server. `No` (default) - Disable the use of a proxy server.
`ProxyServer`	Proxy server options in the format: [`<user>[:<password>]@]<proxy server address>[:<port>`]. When connecting via an HTTP proxy, we recommend to use a separate account that is not used to sign in to other systems. An HTTP proxy uses an insecure connection, and the account may be compromised.	—
`MaxEventsNumber`	The maximum number of events stored by the application. When the specified number of events is exceeded, the application deletes the oldest events.	Default value: 500000. If 0 is specified, events are not saved.
`LimitNumberOfScanFileTasks`	The maximum number of custom scan tasks that a non-privileged user can simultaneously start on the device. This setting does not limit the number of tasks that a user with root privileges can start.	0–4294967295 Default value: 0. If 0 is specified, a non-privileged user cannot start custom scan tasks. If you installed the application interface package when installing the application, the `LimitNumberOfScanFileTasks` settings has the default value `5`.
`UseSyslog`	Enable logging of information about events to syslog Root privileges are required to access syslog.	`Yes` — Enable logging of information about events to syslog. `No` (default value) — Disable logging of information about events to syslog.
`EventsStoragePath`	The database directory where the application saves information about events. Root privileges are required to access the default event database.	Default value: /var/opt/kaspersky/kfl/private/storage/events.db.
`ExcludedMountPoint.item_#`	The mount point to exclude from the scan scope. This exclusion applies to the File Threat Protection component and the Removable Drives Scan task, and is also configured for scan tasks (of the ODS type). You can specify several mount points to be excluded from scans. Mount points must be specified in the same way as they are displayed in the `mount` command output. The `ExcludedMountPoint.item_#` setting is left unspecified by default.	`AllRemoteMounted` — Exclude all remote directories mounted on the device using SMB and NFS protocols from file operation interception. `Mounted:NFS` — Exclude all remote directories mounted on the device using the NFS protocol from file operation interception. `Mounted:SMB` — Exclude all remote directories mounted on the device using the SMB protocol from file operation interception. `Mounted:<file system type>` — Exclude all mounted directories with the specified file system type from file operation interception. `/mnt` — Exclude objects in the /mnt mount point (including subdirectories) from file operation interception. This directory is used as the temporary mount point for removable drives. `<path that contains the` `/mnt/user` `or` `/mnt//user_share>` — Exclude objects in mount points whose names contain the specified mask from file operation interception. 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. To exclude the mount point `/dir`, you need to specifically indicate `/dir` (no asterisk). The mask `/dir/` excludes all mount points at the level below `/dir` but not `/dir` itself. The `/dir/*` mask excludes all mount points below the level of `/dir` but not `/dir` itself. You can use a single `?` character to represent any one character in the file or directory name.
`MemScanExcludedProgramPath.item_#`	Exclude process memory from scans. The application does not scan the memory of the indicated process.	`<full path to process>` – Do not scan the process in the indicated local directory. 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.
`UseOnDemandCPULimit`	Enables a limit on CPU resource usage by scan tasks of the ODS type.	`Yes` to enable the CPU usage limit for ODS tasks. `No` (default): disable CPU usage limits for tasks.
`OnDemandCPULimit`	The maximum utilization of all processor cores (as a percentage) when running tasks of the ODS type.	10–100 Default value: 100.
`BackupDaysToLive`	Time period for storing objects in the Backup storage (in days). After the specified time has elapsed, the application deletes the oldest backup copies of files. To remove the object retention limit, set 0.	0–10000 0–unlimited retention. Default value: 30.
`BackupSizeLimit`	Maximum Backup size in MB. When the maximum Backup storage size is reached, the application deletes the oldest backup copies of files. To remove the Backup size limit, set 0.	0–999999 0–unlimited size. Default value: 0.
`QuarantineBackupFolder`	Path to the Backup directory. You can specify a custom Backup storage directory that is different from the default directory. You can use directories on any device as the Backup storage. It is not recommended to assign directories that are located on remote devices, such as those mounted via the Samba and NFS protocols. If the specified directory does not exist or is unavailable, the application uses the default directory.	Default value: /var/opt/kaspersky/kfl/common/objects-backup/ Root privileges are required to access the default Backup storage directory.
