Click Advanced Settings.
In the Scan technologies block, select the check boxes next to the names of technologies that you want to use for file threat protection:
Use 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.
Use 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).
