I don't normally visit this forum but I saw your post.
Can you just clarify, when you clicked the CNET Tracker link to update CCleaner, you were in fact offered Malwarebytes' Anti-Malware as a download instead?
It might help the CNET Tracker team to hunt down any errors.
Hi, got a generated note that there was a new version of CCleaner 3.16.1666 to download. When I clicked on the link to the CNet download it came up as Malwarebytes, which I happen to have, but wanted to let you know about this. First time I ever saw this happen.
