Cracked CCleaner Pro used as bait for malware trap But I have to note that millions of users still swear by CCleaner. Microsoft had even classified the part as a potentially unwanted program (PUP) for a short time (see Windows Defender flags CCleaner as PUP – Part 1). I don't recommend CCleaner – it's a kind of snake oil. And AVAST was bought by Norton in 2021 (see Avast is bought by Norton for 8.6 billion US dollars).

has belonged to Czech antivirus provider AVAST since 2017.

According to the manufacturer, the program has been downloaded more than two and a half billion times by 2020. In addition, there are other versions for Windows, which are offered for a fee as Business Solutions. CCleaner is a free optimization program for Windows, macOS and Android operating systems.
