Other virus scan settings

In addition to configuring the basic virus scan settings, you can also use advanced settings:
Enable iChecker technology - uses technology that can increase the scan speed by skipping objects that have not been altered since the last scan, provided that scan settings (threat signatures and settings) have not changed. Information about this is stored in a special database.
If you have an archived file that the program scanned and assigned the status of not infected, the next time, the program will skip this archive, unless it has been altered or the scan settings have been changed. If the structure of the archive has changed, because a new object has been added to it, if the scan settings have changed, or if the threat signatures have been updated, the program will scan the archive again.
There are limitations to iChecker: it only applies to objects with a structure that Active Virus Shield recognizes (for example, .exe, .dll, .lnk, .ttf, .inf, .sys, .com, .chm, .zip, .rar).
Enable iSwift technology - use technology that can increase scan speed by only scanning new and altered objects. There are limitations to iSwift: it only applies to objects in NTFS file systems.
Using the iSwift technology is not possible on computers running Microsoft Windows 98SE/ME/XP64 operating system.
Show detected threats on the "Detected" report tab - display a list of threats detected during the scan on the Dangerous objects tab of the report window. Disabling this function may be appropriate for special scans or, for example, text collections to increase the scan speed.
