1. Open the Kaspersky Security Center Administration Console.
2. In the console tree, select Tasks.
3. Select the scan task and double-click to open the task properties.

   If necessary, create the Malware Scan task.

4. In the task properties window, select the Settings section.
5. In the Security level block, click the Settings button.

   This opens the scan task settings window.

6. In the Optimization block, configure the scan settings:
   • Scan only new and modified files. Scans only new files and those files that have been modified since the last time they were scanned. This helps reduce the duration of a scan. This mode applies both to simple and to compound files.

     You can also configure scanning new files by type. For example, you can scan all distribution packages and scan only new archives and office format files.

   • Skip files that are scanned for longer than N sec. This sets a time limit for scanning a single object. After the specified amount of time, the application stops scanning a file. This helps reduce the duration of a scan.
   • Do not run multiple scan tasks at the same time. Postponed start of scan tasks if a scan is already running. Kaspersky Endpoint Security will enqueue new scan tasks if the current scan continues. This helps optimize the load on the computer. For example, let's assume that the application has started a Full Scan task according to the schedule. If a user attempts to start a quick scan from the application interface, Kaspersky Endpoint Security will enqueue this quick scan task and then automatically start this task after the Full Scan task is finished.
7. Click Additional.

   This opens the compound files scanning settings window.

8. In the Size limit block, select the Do not unpack large compound files check box. This sets a time limit for scanning a single object. After the specified amount of time, the application stops scanning a file. This helps reduce the duration of a scan.

   Kaspersky Endpoint Security scans large files that are extracted from archives, regardless of whether the Do not unpack large compound files check box is selected.

9. Click OK.
10. Select the Additional tab.
11. In the Scan technologies block, select the check boxes next to the names of technologies that you want to use during a scan:
    • iSwift Technology. This technology allows increasing scan speed by excluding certain files from scanning. Files are excluded from scans by using a special algorithm that takes into account the release date of Kaspersky Endpoint Security databases, the date when the file was last scanned, and any modifications to the scan settings. The iSwift technology is an advancement of the iChecker technology for the NTFS file system.
    • iChecker Technology. This technology allows increasing scan speed by excluding certain files from scanning. Files are excluded from scans by using a special algorithm that takes into account the release date of Kaspersky Endpoint Security databases, the date when the file was last scanned, and any modifications to the scan settings. There are limitations to iChecker Technology: it does not work with large files and applies only to files with a structure that the application recognizes (for example, EXE, DLL, LNK, TTF, INF, SYS, COM, CHM, ZIP, and RAR).
