It seems that by upgrading premium anti virus from the free one (2 years ago) a clean up program was included that I never used by the way. Canceled the premium anti virus but did not take notice of the clean up program that has to be canceled as well, for this reaason I just got billed 59,99€ via credit card for a re newal off the clean up software that was never installed in the first place! Pay attention to this when canceling your premium avast antivirus software and look out for atached software that was probably included in the package even never installed! They will bill you and there is nothing you can do!. Be warned ...
As far as I'm aware, Avast Cleanup Premium is not part of the the Avast Premium Antivirus program, though it and Avast Free have a cleanup component included.
But it only reports cleanup issues in the hope that you will purchase the paid Avast Cleanup Premium product.
Did you ever signup for the trial version of Avast Cleanup Premium, as that would require completing a payment mandate that would kick in at the end of the trial and upon renewal.
What does your Registration Information say you have for your installation (right click the avast tray icon - Registration Information).
