MSE ran today and for the first time used 99 - 100 % of my cpu and ran forever. The only way I could get it to stop was to reboot. Attempted to remove MSE. It isn't displayed in Add/Remove programs but the folder is visible and all files are intact under Program Files\Microsoft Security Client. I downloaded and ran the bleeping computer MSE Removal Tool. The tool ran but the MSE folder and files are still intact. Any suggestions for removing MSE would be greatly appreciated.
