Appendix E - File types list overview

 

Applies to: Microsoft Antigen

Topic Last Modified: 2007-09-27

This is a list of the file types that are used when creating file filters to detect files based solely on their content type. The program log number is reported in the Antigen program log when the associated file type is identified by a virus scanner or a file filter. For more information about detecting files by type, see “Filtering by file type” in Chapter 12 - Using file filtering.

noteNote:
When a Microsoft® Office file (a PowerPoint®, Access, Excel®, or Word document) is embedded in another Office file, its data is included as part of the original Office file. These files are not scanned as individual files. However, if another file type (such as .exe) is embedded in one of these files and that file is subsequently embedded in an Office file, it will be detected and scanned as a separate file. (The .exe extension, however, is still visible because the icon is a GIF file that cannot be deleted. If you click on the file, the icon will be replaced with the correct TXT icon.)

OPENXML

83

OpenXML file.

This file type applies to Office Word, PowerPoint, and Excel 2007 files only. The Scan Doc Files As Containers settings in General Options (for Manual, Internet, and Realtime scan jobs) do not apply to Office 2007 files because these are always scanned as containers. Although OpenXML files are essentially ZIP containers and the individual files inside are scanned by Antigen, settings that affect ZIP files do not apply to them. OpenXML documents have an XML-based schema that Antigen cannot modify if an infection is found. Therefore, if an infection is in a file that is part of the XML schema, the file is not cleaned and the entire OpenXML document is deleted. However, if the infected file is not part of the XML schema, then Antigen will attempt to clean just that infected file (replacing it with the Deletion Text) and leave the rest of the OpenXML document intact. If it cannot be cleaned, just that file will be deleted. However, in practice, Office 2007 does not open any OpenXML file containing files that are not part of the XML schema.
