In the File types section, you can select types of objects that Kaspersky Internet Security should scan. The default settings in this section depend on the selected level of security.

All files

Kaspersky Internet Security scans files of all formats and extensions.

Files scanned by format

If you select this option, Kaspersky Internet Security scans only files that can be infected by a virus. Prior to scanning an object for viruses, its internal header is analyzed in order to determine the file format. During the scan, file extensions are also taken into consideration.

Files scanned by extension

In this case, Kaspersky Internet Security scans only files that can be infected by a virus. The file format is determined based on the extension of a file.

Files without extensions are always scanned, regardless of the file type selected in the File types section.

In the Scan optimization section, you can select the settings that allow reducing scan time.

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. This scan mode applies both to simple and compound files.

Skip objects scanned longer than

This check box enables / disables the time limit for scanning an object. When the specified time interval elapses, file scanning is discontinued, and Kaspersky Internet Security skips the file.

Selecting this check box causes the scan to stop after 30 seconds by default.

The Scan of compound files section contains a list of type of compound files that Kaspersky Internet Security scans for viruses and other threats. The values of the default settings in this section depend on the security level set and the scan type selected (full scan, selective scan, or quick scan).

Scan archives

This check box enables / disables scanning of RAR, ARJ, ZIP, CAB, LHA, JAR and ICE archives.

One or several file(s) packaged into a single file through compression. A dedicated application, called an archiver, is required for packing and unpacking data.

Scan installation packages

The check box enables / disables scanning of installation packages.

Scan 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 Internet Security.

An object attached to another file or embedded into another file through the use of the Object Linking and Embedding (OLE) technology. An example of an OLE object is a Microsoft Office Excel spreadsheet embedded into a Microsoft Office Word document.

Parse email formats

This check box enables / disables the option for Kaspersky Internet Security to scan files in email formats and mail databases.

If this check box is selected, Kaspersky Internet Security parses the email format file and analyzes each component (body, attachments) for viruses.

If this check box is cleared, Kaspersky Internet Security scans the email format file as a single object.

Do not unpack compound files larger than

If this check box is selected, Kaspersky Internet Security excludes from scanning compound files larger than the specified limit (except larger files extracted from archives).

If this check box is cleared, Kaspersky Internet Security scans compound files of all sizes.

In the Scan methods section, you can select methods that Kaspersky Internet Security should use when scanning the computer. The default settings in this section depend on the selected level of security.

Signature Analysis

When performing signature analysis, Kaspersky Internet Security uses databases that contain descriptions of known threats and ways of neutralizing 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

This check box enables / disables heuristic analysis during virus scanning.

A technology for detecting threats about which information has not yet been added to Kaspersky databases. The heuristic analyzer detects objects whose behavior in the operating system may pose a security threat. Objects detected by the heuristic analyzer are considered to be probably infected. For example, an object may be considered probably infected if it contains sequences of commands that are typical of malicious objects (open file, write to file).

Slider

The slider allows you to adjust 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 actions found within executable files recommended by the experts of Kaspersky.
Deep scan. Heuristic analyzer performs more operations found inside executable files. The probability of threat detection in this mode is higher. Scanning consumes more system resources and takes longer.

The slider is available if the Heuristic Analysis check box is selected.

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 Internet Security 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.
