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).
