After accepting the latest update and rebooting my PC I am not getting an error message that there is an Error Starting Program A required .DLL file, ACWCMNS.DLL was not found. How do I get this dll or redo the updates so I can get Avast up and running again?
Hmm, it seems the installation was badly corrupted somehow… ???
I would suggest to download the full installer and use it to repair/reinstall your avast.
