A while back, ccleaner was hacked... and yes i was using the software at the time lol
I think they are owned by avast now, so maybe their security is better now? I would still avoid regardless.
Also I concur Bleachit -- perfect alternative.

 

thanks,how do i run the portable version?
its ok i see an .exe inside the folder,i guess thats what i run

 

You need this Portable one: See the pictures

The portable edition of CCleaner ---> www.ccleaner.com/ccleaner/builds

You can also move this file to your desktop; it will start immediately when you click on it, and the application will be available right away. It doesn't install anything; you can also copy this application to a USB stick for when you're on the go.

Download it and create a folder, example: Portable edition of CCleaner, place the WinRar file in there and extract it (extract here).

of course run exe, Most likely you need the one with the number 64

You urgently need to watch some basic computer literacy tutorials

 

Look, I'm by no means a cyber security expert - I do work in IT and IT security is getting way more demanding - I would not trust an older version of security software to be finding what is out there at the moment, that sounds like a recipe for infection.
I've used CCleaner in the past and it did a thing but I don't trust it now and would not recommend it, as others have mentioned it is less secure and more enshittified.
Is Windows Defender also enabled? If so, it might have deleted it, maybe for good reason. Defender can be a resource hog but is free, built-it and fairly good at what it does. There are other altermatives if you don't like it.
If you're a purist that doesn't want to run AV on your production machine, then air-gap it i.e DO NOT CONNECT IT TO THE INTERNET. At least boot on to an external Windows-on-the-go drive to access the internet that doesn't recognise your main drive, if that's your only PC - Rufus can do this.
At the end of the day, most of the people in this space - you know who you are, if you don't then your're proabably not part of it - take risks to seek the reward of new and exciting software. If you're operating in fairly safe spaces, SS for example, 99% of the time you'll probably be OK, in which case you can white-list some folders or unquarantine some files and you'll probably be fine.
But IMO if you think your system has been compromised then make a note of the compromised software (or at least the last few you've installed) nuke the system (i.e. do a complete reinstall) delete that software and start over. Or pay for some up-to-date security software - which, if you're in this space - is proabably not something you're able or willing to do.
Relying on old versions of security software is, again IMO, just going to bite you in the arse later.

 

nobody needs bullshit software as CCleaner. Deleting it from your disk is the best thing you can do with it.

 

I ran CCLeaner and I disappeared. I hear my computer is running fine now.

 

"CCleaner 6.39.11548 64-bit Portable" works perfectly for me under Windows 11.

I mostly use CCleaner for the software and drive updater. Is there an alternative program for that?

 

I would strongly advise you to use Revo Uninstaller so everything really will be disappeared

 

didnt know about this!! thankss, agree with the portable apps!

 

Stop using that junk it was compromised a long time ago. Use Glary's Utilities.

 

Didn't really know there was one. Personally, I still use a regular piriform version and I only employ the secure erase for recycle bin, the user-programmable clean function (it cleans ONLY what I tell it to clean and where), and the startup editor. The reg cleaner, the presets for nuking files in sensitive areas, updater, disk analyzer, system restore, drive wiper, dupe finder, any network access, etc is all turned off along with the rest of the other "stuff" except for what I mentioned previously. Don't really see where a Technician edition would really be of any benefit... I have never had it doing anything on its own (i.e. automatically cleaning, or loading at start-up, etc).

ANY of the post-piriform versions should be avoided. The problems arise on win10/11 when attempting to run older CC versions (i.e. piriform's) - the stupid compatibility garbage in the winOS will prevent them from working. I guess that also goes for more stuff other than ccleaner as well. Version 5.50 x64 is the oldest piriform version that seems to run properly on win10 22H2. It's perfectly safe to run, but I still don't give it network access of any sort nor do I use any of the preset "tools". I never did even when I ran it on win7... I'm willing to bet the "other tools" mentioned here as alternates for CC probably have similar functions to CC in them as well. I would not allow those tools loose on my system any more than I would CC. Other than the stuff I have CC doing or use it for, there is really no common sense reason for allowing them to do anything further to your system as a whole.

Bleachit and Snappy drivers!

 

Honestly, I find it hard to believe that geeks like the ones on this forum use old, outdated versions of software known for its security flaws. I used it too, and then I gave up because it drove me completely crazy. All the time clicking to clean up, I don't know what. And then you start cleaning the registry! At that point, you need to go out for a beer and talk to some more or less normal people...

 

create an utilities folder. Unpack bleachit in it. Right click on the .exe. Add it to the taskbar. Voilà!

 

Holy crap snappy drivers is 40 gb
