That was my first impression as well. As someone who likes to understand what my computer is doing I was never aware that Windows Defender was anything more than the typical definition based AV. Does this mean that Windows Defender is now something to disable on HIPAA compliant workstations because there is a chance that Defender thinks some medical records look suspicious and it decided to upload them for analysis? But for the home and small business this stuff is amazing. It really continues the anti-"virus" analogy by effectively creating an immune system comprised of most Windows machines.
