The msnetobj.dll library is an ActiveX control used by Microsoft's DRM; it is intended to prevent the owner of a computer from saving or viewing certain files except under limited circumstances, and to prevent the computer's owner from disabling it or interfering with it.

As if that wasn't bad enough, it is also vulnerable to three separate attacks — buffer overflow, integer overflow and denial of service — any of which can compromise your computer's working, leaving your data vulnerable to crooks and vandals.
