As far as I can tell I have never installed LibreOffice (SPotlight and EasyFind both come up empty searching) but just now when my MacbookPro was overheating I ran Activity Monitor and LibreOfficeImporter was the problem. After searching for LibreOffice in vain I restarted and that solved the problem for now, though Activity Monitor still shows this process in its list, just not using and processing time.
How can I find and get rid of this?
