Microsoft Office 2007 files can trigger the following:
- Scan Exception – Security setting violation (Unscannable)
- Extract File Count Limit
- Extract File Size Limit
This happens because Office 2007 uses a new file architecture called the Office Open XML File Format. This new format places the document file in a ZIP file in the first layer.
Hot Fix Build 14440 resolves this issue. Two keys are provided to configure the above scan exceptions for Office 2007 files.
Release date: February 22, 2011
Trend Micro recommends applying patches or service packs instead of individual hot fixes whenever possible.
