MVFilter

MVFilter disinfects OLE documents (Microsoft Word, Excel and PowerPoint) from macro viruses (both VBA and Word Basic). It does this in the same way that all antivirus programs disinfect macro viruses - by removal of the macro. The difference is that MVFilter was designed as a tool, and as such, it can be used for compartmentalization purposes in addition to it's reactive disinfection role. As a compartmentalization tool, MVFilter can be used to proactively prevent all macro virus infections, including new unknown infections, by automatically stripping all macros from OLE documents as they enter a system. This is a reasonable policy since it provides 100%, infallible protection from the fastest grown virus threat in the world in exchange for losing the ability to use macros. Since very few people use macros, this should not be troublesome to them. Users who need macros can use authorized methods to allow the macros they need while still preventing damage from unauthorized macros.

A second use for MVFilter is as part of a document warehouse archival and management system, such as Documentum - MVFilter has successfully interfaced and operated with these systems. Generally, these systems manage hundreds of thousands to millions of critical documents. MVFilter automates the process of document baseline control by providing a consistent format, free of all macros, in addition to preventing attacks.
