No, CCleaner is not good for viruses; it's a system optimization tool, not an antivirus, and while it can remove junk files, it doesn't detect or remove malware, and has a history of security issues, leading Microsoft to flag it as a "Potentially Unwanted Application" (PUA). For virus protection, you need dedicated antivirus software, as CCleaner itself was once compromised by malware and is generally considered unnecessary since Windows has built-in cleaning tools like Disk Cleanup and Storage Sense.
Is CCleaner secure? We take pride in the fact that CCleaner is the world's most popular optimization tool, and deliver regular updates to add improvements, and ensure it stays secure. Although CCleaner is not an antivirus or malware-detection tool, we are part of Avast, a global leader in cybersecurity.
It's true that CCleaner was once hijacked by hackers, but the developers have taken measures to ensure the security of the software, and it is now considered safe to use.
Malware infection
After Piriform was acquired by Avast, in September 2017, CCleaner 5.33 was compromised by the incorporation of the Floxif trojan horse into the distributed program that could install a backdoor, enabling remote access to 2.27 million machines which had installed CCleaner.

Update your security software to make sure you have the latest protections. If you don't have security software, download it. Find recommendations from independent review sites and ask friends and family for recommendations. Run a security scan to remove the malware.

CCleaner is the main product made by London's Piriform, which was bought in July by Prague-based Avast, one of the world's largest computer security vendors. At the time of the acquisition, the company said 130 million people used CCleaner.
It's generally safe to use it for cleaning temporary files, but even that isn't really necessary anymore. Since CCleaner was acquired by Avast, the software has become bloated with ads and unnecessary components. The days when it was a clean, lightweight, and truly useful tool are long gone.
PrivaZer serves as an advanced alternative to CCleaner with advanced options, command-line support, and detailed logging.
