Avast update has blocked dpp.exe

Hi, for some reason Avast update has blocked dpp.exe - now my program wont work, any reason or solution please?

Is there an avast alert displayed, if so can you attach an image of the alert ?

Right click the avast tray icon and select ‘Show last popup message.’ If you haven’t rebooted or had a different message popup since then, it should be available. Otherwise the option will be greyed out, see image attachment, click to expand.
