Using Third-Party Anti-Virus Software

Word, Excel, and PowerPoint now support a new application programming interface (API) that allows third-party anti-virus software to scan and disinfect a document, as well as the template it is based on and any installed add-ins, as the document is opened. For more information about anti-virus software that supports this new API, see the Microsoft Office Anti-Virus Center Web site at http://officeupdate.microsoft.com/Articles/antivirus.htm .
