Nod32 ea config extension Extension

Extensions of files to be scanned for viruses. Extension specifies what kind of data a file contains.

Scan all files

select this option to scan all files by default. If unchecked, the default set of extensions will be scanned (those known to contain malicious code).


typing an extension activates the Add button, which adds the new extension to the list. Click the extension in the list and then click the Remove button to delete the extension from the list.


Extension format

The extension you are adding may not contain any of the following characters: < > : / \ | ” . ; or a space.

When adding an extension, characters known as wildcards can be used to create an extension mask. An extension mask is a string used to generate an output range of file extensions.

Using wildcards to define extension masks:

* – An asterisk (*)
– denotes any number of any characters; meaning it is in effect always until the end of the string. Thus, D* means you are selecting all files of any name that have an extension starting with the “D” letter followed by any combination of characters. If you enter D*T into the Extension: field it will have precisely the same effect as the D* entry.

? – A question mark (?)
– denotes any single character. If you enter D?T into the Extension: field it will denote any extension starting with a D and ending with a T letter with any character in the middle of the string (e.g. DOT, DAT, DLT etc.).

NOTE: Make sure you enter only file extensions/extension masks and not whole file masks (e.g. *.DAT) into the Extension: field.

Do not scan extensionless files

this checkbox excludes scanning of files with no extension
