Hi Andres,
Thanks for bringing this to our attention.
Could you please confirm for me whether once you get this message appear on CCleaner if when you go to Task Manager -> Details you can see MicrosoftEdge.exe running in "Suspended" mode like in the image below:
Also could you please check your Group Policy settings on the PCs that this message appears. We have a guide on CCleaner.com on how to get there and which settings to change:

Please let
