Latest update: August 17, 2020 ID: 5028

This article concerns:

  • Kaspersky Security 10.1.2 for Windows Server
  • Kaspersky Security 10.1.1 for Windows Server
  • Kaspersky Security 10.1.0 for Windows Server

Kaspersky Security for Windows Server uses the iSwift technology, which allows not to rescan files that have not been changed since the last scan.

In the system folder %SYSTEMDRIVE%\System Volume Information the file fidbox.dat is created. The file contains the information about scanned objects that are safe. When a file is deleted, the information about it is removed from the fidbox.dat file. File size depends on the number of scanned objects.

To clear the fidbox.dat:

  1. Open the command line.
  2. Run the command:

The command functions in the following way:

  • When cleaning the fidbox.dat file using the KAVSHELL FBRESET command, protection stays enabled (as opposed to deleting the file manually).  
  • After cleaning the fidbox.dat, server load may increase. Kaspersky Security for Windows Server will scan all accessed objects. Information about scanned objects is added to the file again. Next time, the iSwift technology will allow to skip an already scanned file if it wasn’t changed.  

If your operating system uses the User Account Control function (UAC), then, to run the KAVSHELL FBRESET command, you must run the command line with administrator privileges.
