Patch 8 is the latest Patch at the moment. The Event Issue was fixed in an earlier patch thats true. However this one could be a Agent Point Product Combination. Normally this was most often seen when running MA 4.5 and VSE 8.7i. As VSE and HIPS have a shared core this might be the same outcome. From this point i assume you see the events disappearing when removing Hips and if it is a combined product issue they would come back when upgrading vse to 8.7 and not installing hips.
If that would be correct a case should be opened for McAfee Agent Team. As far as i know a fix from Agent side is beeing worked on but if it turns out to be Hips only get a case opened for HIPS.
