For a long time CCleaner has been the most popular system-cleaning tool for Windows, extending its reach to other platforms like macOS and Android phones. However since security giant Avast acquired it last year, it's been a stormy ride that's had many doubting how effective or trustworthy the tool really is.

While CCleaner has certainly growed up since its "crap cleaner" days, it's certainly gotten more bloated over the years as well. Going from 6MB in February 2016 to around 15MB around its v5.41.x release in March this year.

You may recall last summer (two months after being acquired by Avast), it was disclosed that the tool had been infected with Floxif malware. Nevertheless, to be fair, this has happened to many other developers, big and small. On the other hand, users had long been complaining about bundled software and popup ads appearing in the utility. Most recently, just last month, the company was forced to pull the latest update following an outcry over privacy issues and obscure tactics to keep the utility running in the background.
