Extract all streams from OLE-structured storage documents for scanning
Certain Microsoft files (such as Microsoft Word and Excel documents) are object linking and embedding (OLE) structured storage documents. OLE is a compound document standard developed by Microsoft. It enables objects to be created with one application and linked or embedded in a second application. In this type of structured storage document, data is stored in a number of streams. Only certain streams typically contain the content that can contain viruses. Symantec Protection Engine is configured by default to extract and scan all streams. Performance might be adversely affected depending on the number (and content) of files to be scanned.
