Yes, but to be fair this is not the first time. I can now download and install various CCleaner installer versions without a peep from defender.ĭisclosure - Yes I am a moderator on the CCleaner forum, not an employee but as mods we do get some inside information that others don't see. (One of the offers is for CCleaner Browser, a Chromium based browser - surely they don't see it as a possible rival to Edge Chromium?)

So it appears that MS's real issue is with the installer offers and not the reg cleaner.

The various (Slim, Pro, Enterprise, etc.) installers that did not contain these offers were not flagged, even though they install the same CCleaner with the same reg cleaner included. It is interesting to note though that the only CCleaner installers they were flagging were the ones that contained bundled offers. MS are supposed to have lifted the block now, but some users may still see it flagged as a PUA.Īgreed that the registry cleaner should be removed from CC, (been telling them that for years now), and ostensibly this is why Microsoft say they are/were flagging CCleaner.
