Found the following folders in C:ProgramDataMicrosoft:
Microsoft Security Client
Microsoft Security Essentials
Microsoft Standalone System Sweeper Tool
I have uninstalled MSE and installed a different AV program. At least 1 if not all of these appear to be remnants of my former MSE install. Is it OK to delete these? Someone who has NEVER had MSE installed on their PC could see if any of these folders exist on their PC as one possible test for deleting these.
Thanks
