my download of ccleaner professional is being blocked/distorted

Recommended Posts

My last re-purchase of CCleaner professional will not load properly 

I re-purchased it three (3) times and the result is the same; it will not load properly.

You have an enemy out there and they don't want your service in the public domain 

what can i do, find another service and uninstall yours?

Is it being blocked by your Anti-Virus perhaps?

Do you use Windows Defender?

What happens when you try to install it, or is it the download you have a problem with?

I suggest you contact Piriform directly regarding how much money you have spent trying to get this to work


Try installing the Slim Build from here (last in list)


You can convert it when installed by going to Options..About and pressing the button to convert to Pro

This could be the problem. I have "Avast" security, anti-tract, cleanup & premium installed. Should I un-install them-?

Avast wouldn't/shouldn't block it. (CCleaner is now owned by Avast).

Can you tell us exactly (which website) you are trying to download/purchase CCleaner from?

Also check Windows Settings>App and browser control>Reputation Based protection settings, to see if this has been turned on:
(A Windows update has turned it on for some people).
