About MS Office files in Symantec Protection Engine
Previously, Symantec Protection Engine was not able to repair the threats that were embedded in MS Office files and used to block access to such files. From version 7.0 onwards, Symantec Protection Engine's scanning capabilities have been enhanced for such office files. Symantec Protection Engine is now capable of scanning the file and can also repair or delete the embedded content. Thus, you would now be able to retrieve the clean contents from the file.
Symantec Protection Engine supports the following formats:
OLE inside OLE
Objecting Linking and Embedding (OLE) formats likes doc, xls, and dot
Object Linking and Embedding (OLE) Native formats like exe, com, jpg, dll, and txt
Package objects like docx, xlsx, docm, dotm, and xlsb
