Actually just updated Libre office to latest version, and Malwarebytes no longer blocks it. Subsequently updated malwarebytes to the latest version, and libraoffice is still able to start. Having seen this in the past I will keep your suggestion in mind if this happens again. Thanks for your help

As this setting is already checked, i.e. the same as you show, are you sugesting I un check it?

Actually version is 4.1.11, from start menu folder

Trying to open a .ods file (Libreoffice spreadsheet) or trying to open the application from the start menus I get an Exploit blocked from Malware bytes. Report attached, not sure adding the executable would help. Not sure of the Libreoffice version, might not be the latest, but not far off. Can't open it to check. Thanks Hugh FPReport.txt
