In the File types section, you can select types of files that File Anti-Virus should scan. The default settings in this section depend on the selected level of security.
All files
File Anti-Virus will scan all files without exclusions (all formats and extensions).
File Anti-Virus considers files without extensions to be executables; they are always scanned, regardless of which type of files you have selected for scanning.
Files scanned by format
If you select this option, File Anti-Virus scans only files which a virus could infiltrate. Before searching for viruses in a file, its internal header is analyzed to determine the file format (TXT, DOC, EXE, etc.). During the scan, file extensions are also taken into consideration.
File Anti-Virus treats files without extensions as executables. File Anti-Virus always scans them, regardless of the file types you have selected for scanning.
Files scanned by extension
In this case File Anti-Virus scans only potentially infectable files. The file format is determined based on the extension of a file.
File Anti-Virus considers files without extensions to be executables; they are always scanned, regardless of which type of files you have selected for scanning.
Edit protection scope
Clicking this link opens the File Anti-Virus protection scope window.
The Scan methods section is designed for selecting methods that File Anti-Virus should use to scan the computer. The default settings in this section depend on the selected level of security.
Signature Analysis
Signature analysis uses the Kaspersky Anti-Virus database, which contains descriptions of known threats and methods for eradicating them. Protection using signature analysis provides a minimal acceptable security level.
As recommended by Kaspersky experts, the application always has this analysis method enabled.
Heuristic analysis
Slider
Changes the level of heuristic analysis. The heuristic analysis level sets the balance between the thoroughness of searches for threats, the load on the operating system's resources, and the time required for scanning.
The following heuristic analysis levels are available:
- Light scan. Heuristic analyzer performs fewer operations found inside executable files. The probability of threat detection in this mode is somewhat lower. Scanning is faster and less resource-intensive.
- Medium scan. Heuristic analyzer performs the number of instructions found within executable files recommended by the experts of Kaspersky.
- Deep scan. Heuristic analyzer performs more operations found in executable files. The probability of threat detection in this mode is higher. Scanning consumes more system resources and takes longer.
The Scan optimization section is designed for selecting methods that allow reducing the scan time. The default setting value in this section depends on the selected level of security.
Scan only new and changed files
This check box enables / disables the scanning only of new files and those files that have changed since the last time they were scanned. File Anti-Virus scans both plain and compound files.
The Scan of compound files section contains the list of compound files which File Anti-Virus checks for viruses. The default setting value in this section depends on the selected level of security.
Scan archives
This check box enables / disables scanning of RAR, ARJ, ZIP, CAB, LHA, JAR and ICE archives.
Scan installation packages
The check box enables / disables scanning of installation packages.
Scan embedded OLE objects
This check box enables / disables scanning of OLE-objects embedded in files (such as Microsoft Office Excel® spreadsheets or macros embedded in Microsoft Office Word files, email attachments) by Kaspersky Anti-Virus.
Advanced Settings
Clicking this button opens the Compound files window. In this window, you can configure scanning of compound files.
In the Scan mode section you can select a condition that will trigger file scanning by File Anti-Virus.
Smart mode
In this mode, File Anti-Virus scans an object based on the analysis of actions taken on the object (default mode).
For example, when working with a Microsoft® Office document, Kaspersky Anti-Virus scans the file the first time it is opened and the last time it is closed. Intermediate operations that overwrite the file do not cause it to be scanned.
On access and modification
In this mode, File Anti-Virus scans objects upon an attempt to open / modify them.
On access
In this mode, File Anti-Virus scans objects only upon an attempt to open them.
On execution
In this mode, File Anti-Virus only scans objects upon an attempt to run them.
In the Scan technologies section you can select a file scan technology.
iSwift Technology
This technology is a development of the iChecker technology for computers using the NTFS file system.
There are limitations to iSwift Technology: it is bound to a specific file's location in the file system and works only with objects in the NTFS file system.
This check box enables / disables the use of iSwift technology.
iChecker Technology
This technology allows increasing scan speed by excluding certain files from scanning. Files are excluded from the scan using a special algorithm that takes into account the release date of Kaspersky Anti-Virus databases, the date when the file was scanned last, and any changes made 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).
This check box enables / disables the use of iChecker technology.
In the Script scanner section, you can enable scanning of scripts and other objects using the Antimalware Scan Interface (AMSI) technology.
Scan scripts using Antimalware Scan Interface (AMSI)
The check box enables or disables scanning of scripts and other objects using the Antimalware Scan Interface (AMSI) technology.
Manage exclusions
Clicking this link opens the Exclusions window. In this window, you can generate a list of scripts and other objects that Kaspersky Anti-Virus will not scan using the Antimalware Scan Interface technology.
