Whenever I run ccleaner (current version on Windows10 Pro 64-bit) I get multiple errors showing up in the Event Viewer. Source is shown as ESENT, and they all say basically "ccleaner tried to access XXXXXXXXX file and error occurred or was unsuccessful". I never saw this before using Windows 7, was wondering if anyone else has seen it?
That's your antivirus, you need the tell the security program that ccleaner is trusted. I don't use ESENT so I can't give you instructions on how to do this, but I'm sure there are instructions for it.
Do you have MS search checked off to clean in ccleaner? Have you only run ccleaner's cleaning routine, or did you also do registry. If the latter did you pay attention to what you removed?
