Believe me PWT999, I would tell you if I knew as it was driving me nuts as well!!! I had also put in a Support Ticket but had only received the acknowledgement in return. I assumed when the problem seemed to clear, that they had done something at their end. I had previously like you tried various settings and unpinned the popup etc. The current situation is that I only have a "slight issue" now on Desktop A---my main PC. I have Desktop A (Win10Pro), LaptopB (Win10Home), Desktop C (Win10 Pro) and Desktop D (Win10 Home). All are at the same version--1809 Build 17763.194. I only run Windows Defender, Malwarebytes Premium and CCleaner Pro. Desktop A this morning at power up displayed the popup and I didn't touch anything. It slowly faded before finally disappearing after about 10 seconds. Firing up CCleaner did not bring it back. Neither did a power down and a power up. Don't know if that'll happen tomorrow but will be going out shortly so will try powering it up later. Not much time at the moment. Took snapshots of what settings I have and also what cookies I keep. I remember removing the Avast one previously --but that was before I realised Piriform had been taken over. It is on two of them. Attaching snapshots in a zip file. Hope you can access it--if not I'll post them individually. Screenshots.zip

Does anyone have an answer for this? It really is an annoyance that I don't need. Or is the only solution to remove CCleaner as PWT999 has done? Update:- Problem seems to have been corrected----I am no longer getting the popup when I switch on my PC's. Have checked four machines. I think that there should be an option as to whether you get these notifications or not as PWT999 suggested in his original post.

Since MWB haven't yet released the update to fix this, then the problem is still there. I have no problems in using the "temporary fix" they give, as in my case, CCleaner is the only program that is affected. All the other programs I use update fine. I'm quite happy to wait on the update from MWB.

Found my answer in this posting by Ebcus. Thanks. I run Malwarebytes and it recently updated to 3.5.1 which has introduced the problem. I temporarily disabled the Ransomware Protection and clicked on the Update now. Everything proceeded as it used to do and CCleaner updated finel.

I have used CCleaner Professional for years now with no problems updating. The last couple of updates that have been released have failed to automatically install. They give an error as shown in attached. In the FAQs I found the explanation that one has to be the Administrator-----I am logged in as an Administrator. I have licences for 5 PC's (family members) and it is the same on all 5 P.C.s. This error now means I have to uninstall the current version and then download/install the Free version, untick the install Avast antivirus and reapply licences. Also have to save the ini file to prevent having to restore cookies I want to keep. It all seems to have happened since the Windows 10 April Update, but that might have nothing to do with it. This is turning into a painful process given that there might be an update monthly!!! As I stated---the updating worked perfectly previously.
