Why You Should Stop Using CCleaner on Windows Right Now
Pinterest Whatsapp

Some Windows software has become so ingrained into PC users’ minds that we don’t think twice to recommend them. Unfortunately, this leads to major issues when a popular tool goes rogue.

That’s exactly what’s happened with CCleaner. Once everyone’s favorite Windows maintenance utility, its increasingly shady behavior means that you should now leave it in the dust.

Here’s why you can’t trust CCleaner anymore, and what to replace it with.

What’s Wrong With CCleaner?

CCleaner, once a tidy app with no history of issues, has had two major problems in less than a year. This is unfortunately not surprising after Avast purchased CCleaner developer Piriform in July 2017.

CCleaner’s New Monitoring

The first is a new behavior in CCleaner version 5.45. Dubbed “Active Monitoring”, it’s a fairly standard feature that collects anonymized information about your system. You can disable it to turn the feature off—or can you?


As it turns out, if you disable Active Monitoring in CCleaner, the software automatically re-enables it after you reboot or reopen CCleaner. This is extremely suspicious behavior and though Piriform has backpedaled on it, upset users are fleeing in droves.

Additionally, the new version of CCleaner is much harder to quit. When you click the X to close the software, it instead minimizes to your System Tray. If you right-click its icon, there’s no option to exit CCleaner. This means you have to close it using the Task Manager, which novice users might not know how to do.


Thus, CCleaner now runs constantly in the background, collecting data for Avast. This is despite most people only opening CCleaner when needed, and requesting to not have this information collected.

CCleaner Distributed Malware

Prior to this, Piriform discovered that CCleaner was hacked and distributed malware CCleaner Was Distributing Malware for a Month CCleaner Was Distributing Malware for a Month CCleaner, a popular piece of security software with a squeaky clean reputation, was distributing malware for the best part of a month. Which means you need to update ASAP. Read More . The 32-bit version was infected with a Trojan that collected information about systems it was installed on. It also had the capability to run code on affected systems.

Thankfully, the company caught it before a widespread attack could happen. But it’s pretty embarrassing that a top-tier security company like Avast had such an embarrassing slip-up.

Since its acquisition by Avast, CCleaner also shows pop-ups harassing you to upgrade to the paid version (which has an automatic cleaning feature). And installing CCleaner sometimes shows an offer to install Avast, which you must uncheck to avoid.

With all this combined, enough is enough. If you’ve had your fill of this obnoxious and shady behavior, it’s time to say goodbye to CCleaner.

How to Uninstall CCleaner

The first step is removing CCleaner from your computer. Doing so is easy. Head to Settings > Apps > Apps & features. Scroll through the list or use the search box to look for CCleaner. Click its name, then choose Uninstall.


What to Replace CCleaner With

The good news is that you actually don’t need CCleaner—Windows 10 has most of its functionality built-in, and you can install other tools for the rest.

Cleaning Junk Files

The longtime Disk Cleanup tool makes cleaning junk files off your system easy. Launch it by typing its name in the Start Menu, then choose the disk you want to scan. Check the boxes for various types of files to clean, and you’re all set.


For a newer interface, you can also access the Storage Sense feature in Windows 10 at Settings > System > Storage. Click Free up space now under Storage sense to remove various types of unnecessary files.


Clearing Caches

Aside from clearing unnecessary files, CCleaner also cleans the cache of your browser and other programs. However, you can clear your browser history, cache, and other information How to Manually & Automatically Clear Your Browser History How to Manually & Automatically Clear Your Browser History The websites you visit leave tracks on your computer. We show you how to delete your browsing history in Firefox, Chrome, Edge, and Internet Explorer. Read More right inside it. Plus, incognito or private modes allow you to browse without saving any information in the first place.

Clearing cache to save space isn’t a long-term solution because your browser will recreate it when needed. The cache helps your browser run more efficiently, so you normally don’t need to clear it unless you run into an issue.


Uninstall Programs and Remove Startup Items

CCleaner’s Tools section includes several functions that duplicate built-in Windows options. To uninstall software, visit the same page you did above to remove CCleaner at Settings > Apps > Apps & features.

Managing startup programs How to Use the Windows 10 Startup Folder: Everything You Need to Know How to Use the Windows 10 Startup Folder: Everything You Need to Know The Windows 10 startup folder lets you manage which programs run at startup. Here's how to find the startup folder and manage its programs. Read More is easy with the Task Manager. Press the Ctrl + Shift + Esc shortcut, or right-click the Taskbar and choose Task Manager, to open it. Switch to the Startup tab and you’ll see everything that runs when you log in. Right-click an option and hit Disable to remove it from startup.

If you prefer, you can also manage these at Settings > Apps > Startup.


Find What’s Taking Up Space

CCleaner has a basic disk analyzer tool that shows you the biggest space hogs on your system. Unsurprisingly, you have better options for disk analysis Need A Disk Cleanup?

Other CCleaner Features

The above are CCleaner’s major features, but you might want replacements for the other minor functions too. In each case, you have options that aren’t obnoxious like CCleaner.

Don’t worry about the Browser Plugins tool—you can manage your browser extensions How to Clean Up Your Browser Extensions (The Easy Way) How to Clean Up Your Browser Extensions (The Easy Way) If you regularly check out cool extensions, then it is probably time to clean up those add-ons that you no longer want, like, or need.

But how do you do that? Read More .

Lastly, don’t worry about losing the Registry cleaner. Registry cleaners are useless, as even removing thousands of invalid entries won’t have the smallest effect on performance. There’s a better chance you’ll break something by cleaning the Registry than fixing it, so leave them alone.


Full Replacements for CCleaner

The above Windows tools and apps should take care of everything you used CCleaner for. But in case you just can’t live without a dedicated cleaning app, we recommend alternatives like atomiccleaner or BleachBit.

Have You Dropped CCleaner Yet?

It’s a shame to see a once-revered Windows tool go so far down the drain. It once was focused on helping you clean up crap, but has turned into a crappy software itself. While Piriform may make changes to the monitoring, these are too little, too late. You should use a tool that respects your privacy and isn’t susceptible to malware.

    You are WRONG about CCleaner. If you go to the Monitoring menu, l turn off system monitoring and active monitoring. Also under Privacy, l turned off usage data to third parties. Every time l start CCleaner, it does not reactivate the settings you pointed out.
    I love the program.

      CCleaner has removed version 5.45 from its website since this article was published. The current version doesn't have this behavior, but I can assure you that it did re-enable the monitoring option before this.

      Whether you want to use CCleaner or not is up to you; I wanted to make people aware of what's going on with it.

    Dear Mr. Stegner,

    I generally keep to the mantra of: "If you don't have anything good to say... shut up and don't say it." I'm sorry but from my perspective, IMHO I disagree with a lot of the information in this article. So I had to stop and comment to hopefully provide some slight words of caution for other users. Look, you're trying to make a living doing these articles. I'm trying to make a living with my own small tech business (it just so happens I'm on hold with HP customer service at the moment, unrelated)... otherwise I don't have the time nor the desire to be a complainer, so I don't want to sit here and bad-mouth you but these things have to be said.

    For others who read this article: 1) for me, CCleaner is NOT grossly encroaching on my privacies as this article infers. I have the most recent version and have absolutely NO issues with it remaining active in my system. Upon closing it, I can watch in Sysinternals ProcExp as the application and ALL of its threads shutdown on-command. 2) I've never had an issue with CCleaner once. Just be careful what you're deleting. Yet during setup, I will readily admit the developers are/were a little conniving because if you don't check boxes appropriately and do a "MANUAL" setup... yes, it will default to "Active Monitoring" and also a whole list of other bloatware, etc. finds its way onto your system. It can easily be avoided. To me, that's just business and they're trying to find any way to get compensation back for releasing what is essentially an almost entirely fully-featured Free Edition of their paid software. 3) Thanks to one of the author's suggestions to "try out" BleachBit... it caused my computer to crash. I will take part of the blame because I'm a little over-the-top for having two Samsung 960 Pro M.2 PCIe drives in RAID0 as my system drive (twice a day backups, one to the network and one to a spinning-disk failsafe drive just in case)... but my RAID partition went from 32% disk usage to system failure because whatever this BleachBit program did... filled my entire storage to 99.999% capacity (and I turned the whole "overwrite" feature off), but *ZAP* - Blue Screen [with an error code I've never, ever seen before] and lo & behold - no boot. With my RAID's "stripe size", settings regarding "Trim" and other SSD lingo, etc... who knows what BleachBit corrupted. But, it's literally been years since seeing a blue screen, and I'm not timid when it comes to my overclocking.

    The true heroes here though are my Computer Engineering degree that taught me to know the pitfalls of being a goon/idiot in order to achieve [albeit slightly inconsistently - V.R.O.C. is SUCH a bummer] 5GB/s seq. Read AND Write + an astonishing 400k-600k IOPS (4K) out of $325 worth of PCIe NVMe drives (friend's employee discount). And another, even more sincere thanks goes out to Macrium and all the beautiful souls who designed and developed that software. Because if anyone reading wants a tip that will prevent them from ending in potential ruins just because of curiously seeing if this article has any merit... figuring you'll just "try things once". I'm not saying it's the best by any means, but Macrium Reflect has been unflappable during the 3-4 years I've used it and it's saved me from my own crazy mistakes and otherwise every time. Do yourself a favor and make a FULL backup with a high-quality Recovery program, in the rare event BleachBit does this to you too. At least I'm not at square one now because of this morning's backup.

    Maybe I'm the last sane man on earth... maybe I did some ninja Windows mods and disabled certain file permissions of CCleaner a long, long time ago and forgot; so somehow none of the Avast-takeover issues have affected me yet. I'm not questioning your credentials, Ben... no disrespect intended. But I wish I hadn't read this article while waiting on hold. More because of the scare-factor and dread that my busy schedule for the day instead would be spent chasing down the root cause/dealing with an unknown RMA process/and unacceptable downtime. But God, do I love Macrium Reflect.

    sudo umount /dev/sda1
    sudo fsck -t ext4 /dev/sda1
    sudo fdisk -l

    So yeah, I'm good......and with the fact that "F-sock" comes standard with just about ANY Linux distro?...I never have to worry about downloading the "latest" version, nor do I EVER have to worry about there being some ind of malware or hidden files waiting to execute behind the scenes! CCleaner?...who needs that crap!?...

    On my Mac, I have used CCleaner then eventually upgraded to CCleaner Professional. Happy and satisfied with it. Had it for a year.

    Eventually, the 1st CCleaner scandal happened... and then this. Good thing, I haven't installed it on my PC yet.

    Will surely try out Atomic Cleaner and Bleach Bit.

    Thank you for this article.

      You're welcome; thanks for checking it out. I can't speak to CCleaner on Mac (I have a MacBook but don't have CCleaner installed on it) but it wouldn't surprise me if there was a similar issue there.

    Thank you for the article, Ben. The major reason I've stuck with CCleaner is the 35-pass secure delete function. Sure, it takes hours, but I'd rather know my deleted files are well and truly written over should something nefarious find its way onto my computer. Is there any comparable product (i.e., free or cheap) that will offer this level of deletion?

    • Ben Stegner
      August 14, 2018 at 2:54 pm

      I understand why you'd want to keep CCleaner around for these functions -- it makes generating a list of installed programs easy too.

      We've covered some programs to securely delete your drives in this article: https://www.ataslaw.com/?product=tag/securely-delete-files-hdd-ssd-windows/

      DBAN (Darik's Boot and Nuke) is a well-regarded one. It's only available run from a CD or USB, so it's not as convenient as CCleaner, but it will obliterate disks depending on the level of deletion you choose.

    Thanks for your article. I had used CCleaner many years ago and it did at the time clean up some problems I had. I had not used it since. Just last week I went looking for their latest version and instead found a program Malwarebytes that seemed to have what I was looking for.

    What I was/am looking for is a program that might analyze my PC and tell me if I have something on the machine that is causing me to not be able to pass 90% of the video reCAPTCHA tests so many sites are using. I have now run Malwarebytes for a week or so and am not sure it found anything or not, but I still have the reCAPTCHA problem.

    Some friends have told me that I have the reCAPTCHA problem because I visit so many web sites in one day, like maybe 300-400 as part of my work. I don't know if that is the case or not, I was hoping (I think I was hoping) that the problem is that Google (reCAPTCHA) is detecting something on my computer, but I sure can't find it. I wonder if any other type of PC analyzer/cleaner might be useful. Anyone have similar problems, with a solution?

    • Ben Stegner
      August 14, 2018 at 2:58 pm

      Google's reCAPCTHAs (the ones where you check a box and sometimes have to select boxes that have street signs or whatever) use an auto-detection system. If your mouse movements seem to be legitimate and coming from a human, the box check is all you need. If they detect bot activity, you have to solve the puzzle.

      When I'm on a VPN connection, I see a reCAPTCHA after making several Google searches in a short time. I would imagine it's probably the same for you -- if you're quickly navigating to all kinds of different sites, you're probably tripping Google's automated detectors. I highly doubt you have an infection on your PC causing that, especially if MB didn't find anything.

    I removed CCleaner about 4 months ago after it, my word and yours, went rogue, By the time I realized what was happening it had already deleted around 80% of my files, including my external WD backup drive. I tried several "undelete" programs and recovered less than 200 MB of it.

    I'm still pretty steamed about the whole thing, but, ya know, freeware and T&C. In the words of the great Sir Sean Connery when a book fell on his head,

    "I can only blame my shelf."

    I have used CCleaner for many years. I recently installed an updated CCleaner version from Piriform's CCleaner website. There was no box to check or uncheck and yet I also got the Avast security program silently and secretly installed. The CCleaner program that is 10.7MB secretly installed the Avast program that is over 230MB.

    I was only alerted to the Avast installation when my Norton Security software detected suspicious activity in an Avast folder on my PC, and since I have never installed Avast I knew there was a problem. I tried to uninstall the Avast software using Control Panel but the uninstall process locked up leaving pieces of Avast all over my PC. I spent some time researching this issue and discovered this was now a common occurrence with CCleaner updates. I had to download the Avastclear.exe program, boot my PC into Safe Mode and then run it to uninstall Avast. Then I had to reboot my PC and look for remaining traces of Avast all over my PC including the Registry.

    This entire episode wasted a couple of hours of my time. I am done with CCleaner. This is absolutely unacceptable. This is the kind of thing that both CCleaner and Avast should be trying to stop, not colluding to make it happen!

      It's amazing how much garbage most free antivirus suites pack in these days, and how hard they can be to remove. The level of hooking into your system they do is why I dropped them for Windows Defender, which has been great.

      Avast was once slick and pretty solid, but it's a mess now. It's a shame.

    I too got furious when Avast released its update, referred to in your article. Obviously, they underestimated the consumer power. The fact that Avast is trying to find a way to make money on their investment, isn't surprising. And the fact that many companies still seem to think that most user are pretty stupid, isn't surprising either. But Avast got it all wrong. Call it greed - if you like.
    Still, they did back down. They realized once again that the endusers rule.
    Let's give them that. Everyone can make mistakes, and yes, this one was major. But now, everything is fine again.
    So, I think your article is unfair, judgemental and much too harsh. 'MakeUseOf' has power through its many readers, and you publish an excellent magazine. But please, manage your power with care, or you may also find users turning their back on you.
    I'm sure Avast has something good in the bag for us in the coming month.
    I'm staying with CCleaner - after they cleaned it.

    • Ben Stegner
      August 13, 2018 at 9:55 pm

      I wrote this article before they put the old version of CCleaner back up. I feel that the company has had multiple issues which warrant CCleaner not worth using anymore, especially because it's not really necessary for most users.

      The malware attack combined with nagware-styled behavior and bundling Avast is enough to negate the software's worth, in my opinion. Readers are free to use CCleaner if they still want to -- I'm just recommending that you use something else now.

      I don't think I was overly judgmental -- the fact that the company did this in the first place says something.

    I've used ccleaner for years and have the paid version. I uninstalled during their hack. I am disappointed to hear they're owned by Avast. That said, the paid version is far superior to the free version, and I plan to continue using it. I periodically run SuperAntiSpyware (used by my local computer repair shop), but ccleaner seems to overall do a great job. I also run Malwarebytes (paid). When I have had a question, ccleaner support has been quick to respond and very helpful. I do appreciate other helpful comments that have been made on this post.

    The Windows Disk Cleanup tool is probably one of the worst programs I have ever used. It can literally take hours just to SCAN for files, not to mention deleting them. And it usually doesn't find a whole lot of files to be removed after waiting forever for the scan to finish.

      Agreed that, at least under Win7 and prior Windows-client OSes, CCleaner does a better job than CleanMgr; and when cleaning GBes of temp. files helps the OS respond faster, that's important.

      I haven't heard of issues with those other tools, but it wouldn't surprise me if Avast added something distasteful to them either. You don't need Defraggler if you have an SSD. I still have Speccy installed; maybe they won't mess with that since it's not as popular as CCleaner.

    This has been covered on other sites. Also, Avast re-released an older version without the objectionable monitoring function that can't be disabled.

    For older versions of CCleaner one only needs to search on the Internet Archive (dot org) and there are plenty of free versions without the problems.

    While using CCleaner one might also search for CCEnhancer which adds lots of other cleaning options.

    And search with startpage dot com! Same info as google, no ads, no tracking and is based in the Netherlands. Why should google track and violate your privacy?

    • Ben Stegner
      August 12, 2018 at 7:25 pm

      If sites never wrote about anything covered on other websites, there wouldn't be much content online! And Avast replaced the main download link with the older version after I wrote this post, so I apologize for not having that in the main post.

      The problem with using an older version of CCleaner is that before long, it will be way out of date and full of its own problems. It won't get security fixes of newer versions, meaning it's a pretty short-term solution.

      You're right for sure -- there are worthwhile alternatives to almost any software!

        August 12, 2018 at 8:13 pm

        Of all of the many years I've used CCleaner the only reason, they issue updates is to try to sell it to you again and again, etc. There really isn't any visible changes in all of the versions I have used except for the frustrating monitoring issue.
        While I am using win 8.1 and 10 I don't just rely on CCleaner. Wise Disk Cleaner is a good backup for what CCleaner misses. And with the CCEnhancer definitions, one gets a lot more options to clean up other files.
        So, CCleaner is just a Madison Avenue-driven update(s) to get you to buy the product when the free (or slim) version works just fine.
        Until I saw on other sites how to obtain earlier versions I stopped demeaning myself for deleting the older version(s) from my 1 Tb backup disk.
        The size of the update files have only changed slightly in the past several years and the size changes are for simply for selling you something you don't want. Nothing on my machines is automatic when it comes to maintenance. If I can't make it manual it goes away with Geek Uninstaller...
        None of the available 'free' options just don't do the same as CCleaner. Perhaps someone in the open source community could come up with something, but in the meantime, using CCleaner older versions is safe.
        Perhaps you aren't familiar with sites like 'older versions' or 'old versions. And there are more sites with similar content. The web/internet archive org is a prime example.
        Take if from me, a senior citizen geek: You really can't go wrong using older versions unless it's something like the old AOL install disks--lol!

    Will uninstall CCleaner. It is now no longer trustworthy. Should not have to unclick to not install unasked for software Also setting up firewall rules to stop a program from spying on you means it not a safe program.

    ... and what about Windows 7? Some people refuse to change to 10!

    "...if you disable Active Monitoring in CCleaner, the software automatically re-enables it after you reboot or reopen CCleaner"

    I had version 5.45.6611 installed and did not see this issue, I had Active Monitoring turned off and it stayed off.

    "Piriform discovered that CCleaner was hacked and distributed malware"

    As anyone knows this is a threat that faces all of us as long as there are "bad actors" (i.e., always) and Piriform and now Avast have taken steps to prevent this from happening again.

    "Since its acquisition by Avast, CCleaner also shows pop-ups harassing you to upgrade to the paid version (which has an automatic cleaning feature). And installing CCleaner sometimes shows an offer to install Avast, which you must uncheck to avoid."

    I have not seen any pop-ups. The offer (or should we call it a threat ;-) to install Avast is annoying, even obnoxious and a pita if you miss it, but I don't think it descends to the level of "shady behavior".

    Since reading the following post on a CCleaner forum I have down graded to version 5.44.6575 until the next update

    It's a known issue, among others, with v5.45.

    Version 5.45 has been officially withdrawn, and you are advised to reinstall v5.44 (or an older version, some have gone back to 5.40).

    5.44 is now the version on the piriform download site: https://www.ccleaner.com/ccleaner/builds

    5.44 and older versions are also available on Filehippo: https://filehippo.com/download_ccleaner/

    I have used crap cleaner since forever and have, on the whole, been very satisfied with it's extreme usefulness.

    It's pretty easy to add a Windows Firewall rule that prevents CCleaner from accessing the network, but that doesn't address the other objections.
