Configuring performance

To configure performance settings for the Real-Time File Protection task:

1. Open the Real-time file protection settings window.
2. Select the Performance tab.
3. In the Exclusions block:
   • Clear or select the Exclude files check box.
     

     Excluding files from scanning by file name or file name mask.

     If this check box is selected, Kaspersky Industrial CyberSecurity for Nodes skips specified detectable objects during scanning.

     If this check box is cleared, Kaspersky Industrial CyberSecurity for Nodes scans all objects.

     By default, the check box is cleared.

   • Clear or select the Do not detect check box.
     

     Objects are excluded from scanning by the name or name mask of the detectable object. The list of names of detectable objects is available on the Virus Encyclopedia website.

     If this check box is selected, Kaspersky Industrial CyberSecurity for Nodes skips specified detectable objects during scanning.

     If the check box is cleared, Kaspersky Industrial CyberSecurity for Nodes detects all objects specified in the application by default.

     By default, the check box is cleared.

   • Click the Edit button for each setting to add exclusions.
4. In the Advanced settings block:
   • Stop scanning if it takes longer than (sec.)
     

     Limits the duration of object scanning. The default value is 60 seconds.

     If the check box is selected, scanning is limited to the specified maximum duration.

     If the check box is cleared, scanning is unlimited.

     By default, the check box is selected for the Maximum performance security level.

   • Do not scan compound objects larger than (MB)
     

     Excludes objects larger than the specified size from scanning.

     If the check box is selected, Kaspersky Industrial CyberSecurity for Nodes skips compound objects whose size exceeds the specified limit during a virus scan.

     If this check box is cleared, Kaspersky Industrial CyberSecurity for Nodes scans compound objects of any size.

     By default, the check box is selected for the Maximum performance security level.

   • Use iSwift technology
     

     iSwift compares a file’s NTFS identifier stored in a database with its current identifier. Scanning is performed only for files whose identifiers have changed (new files and files modified since the last scan of NTFS system objects).

     If the check box is selected, Kaspersky Industrial CyberSecurity for Nodes scans only new files or those modified since the last scan of NTFS system objects.

     If the check box is cleared, Kaspersky Industrial CyberSecurity for Nodes scans NTFS file system objects regardless of the file creation date or file modification date, except for files from network folders.

     The check box is selected by default.

   • Use iChecker technology
     

     iChecker calculates and remembers checksums of scanned files. If an object is modified, the checksum changes. The application compares all checksums and scans only files that are new and have been modified since the last scan.

     If the check box is selected, Kaspersky Industrial CyberSecurity for Nodes scans only new and modified files.

     If the check box is cleared, Kaspersky Industrial CyberSecurity for Nodes scans files regardless of the file creation date or file modification date.

     The check box is selected by default.
