In the Object scan acceleration section you can enable/ disable use of technologies to accelerate the anti-virus scan 

• Use the iChecker technology: the technology allows accelerating the anti-virus scan by excluding from scan the objects that were not changed or modified from the time of the previous scan (if the scan parameters (anti-virus databases and settings) have not been changed). Information about it is stored in a special database.
• Use the iStreams technology: this technology is similar to iChecker. The difference is the following: in iStreams information about the object scan is stored in an additional file stream. iStreams is also applicable to objects of any type, no matter if the structure of the object is already known to Kaspersky Anti-Virus or not.

Note: The iChecker technology has a restriction: it is only applicable to the objects with the structure known to Kaspersky Anti-Virus (e.g., files exe, dll, lnk, ttf, inf, sys, com, chm, zip, rar).

Note: the options values (enabled/disabled) are given for Kaspersky Anti-Virus 5.0 for Windows Workstations functioning in the Recommended mode. Depending on the protection level for a specific on-demand scan task the options change (Protection levels of real-time file scan in Kaspersky Anti-Virus 5.0 for Windows Workstations)
