Yes, decades ago, some registry cleaner were reckless and way too aggressive. It is unreasonable to assume such a popular and useful tool that's been around that long would still be on the market (or, as an included feature) if that harmful as some suggest. CCleaner has been around for close to 20 years.

Having the ability to keep specific cookies during cleanup is invaluable to me.Īnd for the record, the claim that CCleaner's Registry cleaner can be harmful is misleading and totally exaggerated too. If you believe CCleaner is unsafe, then you should use no 3rd party cleaning tool and just stick with Windows own Disk Cleanup. Rather, it was caused by the new owners of Piriform (Avast) sticking their noses in the mix without doing their homework first.

And it should be pointed out the issue that caused the most attention wasn't even caused by the developers of CCleaner (Piriform). And the problems were quickly addressed long ago. First and foremost, the few issues were minor, actually affected only a tiny number of the 10s of millions of users.
