You could be doing yourself more harm than good
Is it a bad idea to use CCleaner?
When you talk to a computer professional (or family member) about how to protect your computer from viruses or malware, he or she will often tell you to install a number of apps to keep your PC secure.
These apps usually include antivirus software and anti-malware apps for desktop and browser. CCleaner is also often recommended.
CCleaner has been a mainstay in protecting Windows computers for years. It was created at a time when Microsoft Windows lacked many built-in protections and features, so CCleaner filled those gaps.
