CCleaner was originally developed by Piriform (a company acquired by Avast in 2017) and Avast had a past of adding some undesirable features to the program.
Avast Software s.r.o. is a Czech multinational cybersecurity software company headquartered in Prague, Czech Republic
In July 2016, Avast acquired competitor AVG Technologies
In late 2019, Avast browser extensions were found to collect user data, including browsing behavior and history, and send it to a remote server. No concrete evidence was found to prove it.
In January 2020, a joint investigation by Motherboard and PCMag found that the Avast Antivirus and AVG AntiVirus Free version were collecting user data, which was being resold to personalize advertising through a subsidiary, Jumpshot. The leaked documents showed that Jumpshot offered to provide its customers with "Every search. Every click. On every site." than 100 million compromised devices. In response, Avast announced on January 30, 2020, that it would immediately shut down Jumpshot and cease all operations due to the backlash of its users' data privacy
On the basis of the information revealed, on 11 February 2020, the Czech Office for Personal Data Protection announced that it had initiated a preliminary investigation
On August 9, 2019, Broadcom Inc. announced they would be acquiring the Enterprise Security software division of Symantec for $10.7 billion, after having attempted to purchase the whole company. The sale closed on November 4, 2019, and subsequently, the company adopted the NortonLifeLock name.
On December 7, 2020, NortonLifeLock, formerly known as Symantec Corporation, announced the acquisition of Avira. The acquisition was closed in January 2021.
Basically, the software has traded ownership a few times, and now Windows 10 and 11 both provide more than enough internally built tools to perform just about any type of maintenance on the computer needed already without 3rd party software. Thus, most computer experts no longer recommend the product.
However, it's your choice if you want to keep and use the program or not. Maybe learn other builtin tools or how to make your own batch files or PowerShell scripts and run Scheduled Tasks that in the end will help you learn a lot more about how your computer works.
