File Block Functionality is pre-installed in Excel, Word and Powerpoint 2007 but you need to read MS articles
http://support.microsoft.com/kb/922849
http://support.microsoft.com/kb/922848
and
http://support.microsoft.com/kb/922847
for instructions on how to enable them on each application.
The first tool to defend against these attacks, called Microsoft Office Isolated Conversion Environment, is meant to protect users running Office 2003 and Office 2007. MOICE works by converting Office 2003 binary files to the Office Open XML format used by 2007 Office, blocking out malicious code in the process. This conversion takes place inside an "isolated environment," which Microsoft said prevents malicious code from running on the computer.
The second tool, called File Block Functionality for Microsoft Office 2003 and the 2007 Microsoft Office system, gives system administrators the ability to define which file types can and cannot be opened by users. This gives administrators the ability to block access to certain files when a specific threat arises, Microsoft said. Microsoft detailed MOICE and File Blocker in a security advisory, recommending that both tools be used to protect against malicious Office documents. The advisory includes links to the necessary files and detailed installation instructions.
