CCleaner v5.45.6611 cannot disable active monitoring in CCleaner Discussion Posted August 1, 2018 · Report reply I don't think it's a bug. I think they thought they'd sneak it in and no-one would notice. They're now saying there'l be a fix in a few weeks. It's easier to go back to an earlier version. You can get earlier versions on FileHippo, just don't let it update.
