BLADE is a new Windows immunization system that prevents surreptitious drive-by download exploits from infecting vulnerable Windows hosts.  BLADE is implemented as a series of kernel extensions, which interrupt the covert binary installation phase of current malware drive-by exploits.  We test BLADE daily against live malicious URL links across the Internet and publicly post our unfiltered and auto-generated results to BLADE's Evaluation Lab.   To date, BLADE's interception logic has demonstrated 100% effectiveness in preventing covert binary installations using the most widely deployed browsers on the Internet. Furthermore, over the past six months we have tested BLADE against the newest 0-day drive-by exploit attacks within days of their release, and none have circumvented BLADE. In our next phase, we will provide a free Internet release of BLADE for public use, which will extend our ability to harvest new malicious URLs and binaries and will help us further explore BLADE's compatibility across a larger range of computing environments and configurations.  Thanks for your interest and your patience.
