When you uninstall MSE, it does not remove the security counter. As indicated above by Zuhl3156, YOU MUST, again, MUST shutdown the security counter. If you do not want to reinstall Microsoft Security Essentials to stop this problem, there is a step which you MUST, I repeat, MUST follow. You might have to reboot your computer for changes Network and Sharing Center -> Change adapter settings -> Right mouse click on said network adapter -> Properties -> Uncheck 'Internet Protocol Version 6 (TCP/IPv6)' -> Press OK. Disabling IPv6 for your current network adapter might keep the error from showing up in theĮvent Viewer. To troubleshoot, please refer to:įinally, you can try to navigate to: C:/program data/microsoft/microsoft security essentials/support/ > then locate the file: 'MSSEOOBE.etl' and simply delete it.įor you second issues, it seems like there are some issues with IPv6 compatibility of either your network adapter or your router, but nothing to really worry about. You used right way to uninstall Microsoft Security Client.Īlso from my research I found similar issue occurred in some Windows 7 systems. I am not sure this problem was caused as you removed Microsoft Security Client in wrong way.
