Answer
Windows Defender has been replaced with Falcon Sensor by CrowdStrike as the default antivirus for faculty and staff on campus. Most operating systems won't inform their user of the change, however some older Windows computers may issue a warning that Windows Defender is not working or unavailable. This means that CrowdStrike has taken over as the primary antivirus. This message can be ignored.
