You are almost certainly mistaking it for MacKeeper, which is what pretty much everyone does when I recommend it. It's really sad because CleanMyMac (CMM) is one of the only cleaning tools I've ever used and can recommended, particularly on a mac. It's surprisingly high quality for a clean up utility. The uninstaller is very convenient for me and I use it often, as it tries to detect configuration files and asks to remove them as well.
