writers. Its latest version introduces a completely new way of code emulation based on binary translation. This new

binary translator helps to bypass anti-emulation tricks used by malware writers. In addition to these improvements,

DNA-based scanning has been significantly updated to allow for better generic detections and address current

malware more accurately.

ESET Live Grid – Using ESET reputation technology, information about scanned files is verified against data from the

cloud-based ESET Live Grid to improve detection and scanning speed.

4.1.1.6.3 Cleaning

The cleaning settings determine the behavior of the scanner while cleaning infected files. There are 3 levels of

cleaning.

4.1.1.6.4 Extensions

An extension is a part of a file name delimited by a period. An extension defines the type and content of a file. This

section of the ThreatSense parameter setup lets you define the types of files to scan.

By default, all files are scanned regardless of their extension. Any extension can be added to the list of files

excluded from scanning. If Scan all files is deselected, the list changes to show all currently scanned file extensions.

To enable the scanning of files without an extension, select Scan extensionless files. Do not scan extensionless

files becomes available when Scan all files is enabled.

Excluding files is sometimes necessary if scanning certain file types prevents the program that is using certain

extensions from running properly. For example, it may be advisable to exclude the .edb, .eml and .tmp extensions

when using Microsoft Exchange servers.

Using the Add and Remove buttons, you can allow or prohibit scanning of specific file extensions. Typing an

Extension activates the Add button, which adds the new extension to the list. Select an extension in the list and

then click Remove to delete that extension from the list.

The special symbols * (asterisk) and ? (question mark) can be used. The asterisk substitutes any character string, and

the question mark substitutes any symbol. Particular care should be taken when specifying excluded addresses,

because the list should only contain trusted and safe addresses. Similarly, it is necessary to ensure that the symbols

* and ? are used correctly in this list.

To scan the default set of extensions only, click Default and click Yes when prompted to confirm.

4.1.1.6.5 Limits

The Limits section allows you to specify the maximum size of objects and levels of nested archives to be scanned:

Maximum object size – Defines the maximum size of objects to be scanned. The given antivirus module will then

scan only objects smaller than the size specified. This option should only be changed by advanced users who may

have specific reasons for excluding larger objects from scanning. Default value: unlimited.

Maximum scan time for object (sec.) – Defines the maximum time value for scanning of an object. If a user-defined

value has been entered here, the antivirus module will stop scanning an object when that time has elapsed,

regardless of whether the scan has finished. Default value: unlimited.

Archive nesting level – Specifies the maximum depth of archive scanning. Default value: 10.

Maximum size of file in archive – This option allows you to specify the maximum file size for files contained in

archives (when they are extracted) that are to be scanned. Default value: unlimited.

If scanning of an archive is prematurely terminated for these reasons, the archive check box will remain deselected.

Note: We do not recommend changing the default values; under normal circumstances, there should be no reason

to modify them.
