Feedback I'm getting from McAfee as expected - - changing Artemis Sensitivity Level from Low to Medium brings more detections. If anything, this enables us to promote that our users should not be visiting 'none-work-related-sites'. I did change the sensitivity level on a few test workstations from Medium to HIGH and VERY HIGH which resulted in some false positives. Note to those running Win8 and Server 2012 - VSE 8.8 P3 makes the Artemis Default level to Medium instead of very low as i'm sure you've seen.
