My aplogies then. Lets see if we can track down what happened. As Dave CCleaner said above Scheduling should not be running in the Free version, you can't even turn it on in Free. One thing he didn't mention above is Smart Cleaning which can run in a limited fashion in Free, and can notify you if there is junk to clean, do you by any chance have that enabled?

Hazelnut asked because the term 'Managed Antivirus' does indicate that it is a network endpoint solution for business. ie. One that is 'managed' on your machine remotely by the company's IT department. And that also makes more sense now that you say that it's from a former business IT consultant. Is your former IT consultant still managing the AV for you? or has it been without any support or updates for a while? You may want to look further into just what it is, and more importantly when was it last updated. If it hasn't been updated for a while then it's almost certainly out of date and not properly protecting you. To get back to the greyed out button in CCleaner - It is likely that this 'managed' AV is blocking the required connection to that particular CCleaner server, network AVs are very keen on restricting unknown connections to protect the business network (employees have a habit of clicking links they shouldn't and letting nasties in), in which case it would need the AV firewall settings changing to allow it through.

Windows 10 21H2 has now been released to market. It is supposed to be being offered as an Optional Update to 'seekers' who use 'Check for Updates' from Windows Settings - I'm not getting it offered that way yet though. It is now the version on the Update Assistant or if you create media from there, - but as that means doing a full reinstall rather than an update then it will take a lot longer if you choose to go that route.

Ah, so it was a message. That is not what I was expecting and I don't believe that CCleaner ran at all. I think that what you saw was nothing to do with scheduling. Especially as you have the Free version which doesn't do scheduling. Instead I think that what you saw was a popup notification, bottom right of your screen, probably offering you a CCleaner licence very cheaply. (It's Black Friday sale time everywhere). It's advertising and some find it annoying, but it's nothing to do with scheduling. If you had CCleaner Pro already then you wouldn't have got it. Occasional advertising is part of the price you pay for using a product, any product, for free. TNSTAAFL as the saying goes.

Thanks I'll look later if I can find what it could be, but am not at home at the moment.

"Suggestedsites.dat" is a Microsoft file and is created when you have enabled 'Suggested Sites' in a Microsoft browser or other Microsoft app. It may be coming from Edge, or some other MS application even though it's showing up as IE in CCleaner. Other apps do use IE's temporary storage location for convinence. The size of 512 KB suggests to me that it's probably empty and is just Windows putting it there in case you want to use it later. See the link below for more about why that happens. Some files like that do come back immediately after cleaning, but as said they have been cleaned and are empty. Have a read of the second half of this for an explanation of what these files are, where they can be coming from, and how you can stop some of that:

This sounds a bit like the 32-bit vs 64-bit issue that the Software Updater could have. If you had one 'bit' version and the other version got an update first you could end up with both versions installed. (Irfanview was one such app where it could happen). That has supposedly now been fixed in CCleaner v5.87, Presumably this KeePass issue is also in the list to be fixed, but of course fixes have priorities and something that is only affecting one or two users may be lower down the list.

MAV? Do you mean Microsoft Defender? (Commonly referred to as Windows Defender). Is your 'Speed' button still greyed out and not working? Is you 'Security' button not grey and working?

I am interested in this. Can you explain what you saw that told you that CCleaner had run by itself? I don't want to ask any leading questions so if you could just say what you saw that would be good.

Ouch; We advise that you don't use the reg cleaner with Win 10 unless you are trying to fix a specific problem. Registry cleaning is not something that should be used just 'because it's there'. So that advice has to go double for Win 11 which is likely to have new registry entries. Many wouldn't use a driver updater either, especially with Win 11, unless trying to fix a specific problem. (And yes, I differ from the official line on that point). To answer your question there is not a telephone line for support. You can email- support@ccleaner.com and they are pretty quick to get back to you to help sort things out. You'll usually get one-to-one help within an hour.

It didn't take much to find him: Sorry I can't comment much on your complaint, but I assume that you are using Health Check and it's downloading software that you don't want. If you use Custom Clean instead then that doesn't even check for software updates, it just cleans the Junk. To set Custom Clean as your default cleaning method use Options>Settings>CCleaner Home Screen>Custom Clean

Sorry I though you meant the desktop icon. As Nergal says CCleaner will only wipe the free space on your system drive (usually that's drive C:). If it let you wipe the entire drive then you would wipe out Windows, and your computer would no longer work.

Unfortunately currently a PC/Mac licence cannot be used with Android. That's because of the way that Google insist that you have to purchase the Android version through the Play Store. (So that they can take their cut).

Do you mean that the desktop icon is not working? If so that sounds like a broken shortcut. (You say "icons" plural, do you have more than one showing?) There are a few ways to fix broken shortcuts. I'd uninstall CCleaner, delete any CCleaner icons if there are any left on the desktop. Then reinstall CCleaner. For simplicity use the 'Slim' installer from here: https://www.ccleaner.com/ccleaner/builds If you have CCleaner Pro then you will probably need to re-register it in Options>About>Upgrade to Pro using your existing licence key.

I suspect that this is a common missunderstanding that we see quite often. I think that what you mean is that you are being logged out of websites, rather than the passwords being deleted. ('Saved Passwords' if ticked will delete all saved passwords altogether from your browser. So you wouldn't usually want to do that and it should normally be left unticked). What logs you out of websites (and closes any open browser tabs) is the Custom Clean option 'Session' - untick that for each browser that you use and Custom Clean will no longer log you out of any websites. Note that those ticks/unticks only apply to Custom Clean, if you use Health Check it does it's own thing and will still clear the session information and log you out of websites. You can change whether CCleaner shows you Health Check or Custom Clean as default by changing Options>Settings>CCleaner Home Screen.

As you note you can have your Downloads, Documents, Pictures, etc. folders on a different drive than the Windows Operating System. That's called 'redirecting' those Standard folders and is common practice when you have a small SSD for the OS and a larger drive for storage. But that isn't a problem for CCleaner and it will scan/clean the right drive without you having to do anything. To explain a bit more: Those Standard folders (and others) are stored in the user profile for each user. That's because each user of that computer has their own set of folders, and they contain different things from any other users of that computer. If that user profile is not stored on the OS drive then Windows knows that, and will 'point' CCleaner or any other application to where it actually is. Windows stores paths like that as variables that applications (and users) can access to save time looking for them. eg. the Windows variable %Userprofile% contains the name of the currently logged in users profile and what drive that profile is saved on. Within that location %Userprofile%\AppData\ contains all your temporary browser (and other application) data. So CCleaner (or any other app) just has to say "Look in %Userprofile%\AppData\ " and it finds the current users application data, it doesn't matter what the username is or what drive that user profile is actually on. As a further example: %Userprofile%\AppData\Local\Microsoft\Windows\Explorer\ Contains your Icon caches, Thumbnail caches, and a couple of logfiles. It doesn't matter what drive it's on or what your username is, using that variable in the pathname will go straight to it. (You can try it yourself - Copy and paste it into the pathname bar of File Explorer, press Enter, and you will be taken there whatever disc it is on). (Note- one exception to all that is if you have manually created your own folders with those names on another drive rather than redirecting Windows to put the standard profile folders there - ie. if you have manually duplicated those folder names outside of your profile - But even that wouldn't be a problem for CCleaner because any application saving data wouldn't use them and would still use the ones in your user profile). The only times that you have to tell CCleaner to look at a different drive is when using certain of the Tools that work with specific drives (DisK Analyzer, Duplicate Finder, Drive Wiper/Wipe Free Space), or when specifying 'Includes' or 'Excludes' in Custom Clean.

Yes, it gets asked a lot so I wrote an explanation about it. Have a read of this about what 'Trackers' actually are, why they (and other files) can come straight back after cleaning, and what you can do to stop some of it happening: (PS. In your case I suspect that your browser is synced, which will bring browser related things back from the cloud as soon as you clean them off your computer).

That is a pretty old installer from March 2019 and has probably been taken off Windows Defenders 'Recognised' list, they do change it to remove old stuff. TBH if you have that old installer you should probably delete it anyway, it's not much use for anything now.

You have a corrupted Recycle Bin, most people get one at some time - it's fairly common and easy to fix. What happens is that Windows throws a wobbly and is remembering/reporting files that have already been cleared as being in the the bin even though they are not there anymore . It's a long standing bug in Windows and has been happening for years. There are various things that can cause it to start. Many people have a corrupted bin but don't even notice because (most of the time) it looks like it's acting as it should, it's only when you look deeper that you can see there's something not right. And as I say it's easy to fix it; See here for how to do that:

Like I said above I think the cause is an occasional glitch in the last 2 Firefox versions, not in CCleaner. From what I've been seeing here, with the last Firefox version and with this one, then sometimes but not always Firefox is not closing like it should do and is leaving some files open. If/when it does that then CCleaner will say that Firefox is still running, because some part of Firefox hasn't been closed properly. (You may also occasionally see the 'Firefox is already open' message when you try to launch Firefox, I've been getting that occasionally with the last 2 Firefox versions). If a Firefox bug is the cause then it's for Mozilla to fix it.

Yes they do, and they are usually pretty quick to help you sort out any problems: Send your email to support@ccleaner.com (Laurence CCleaner also gave it in his post above). It's best if you can use the same email address that you used when purchasing/registering CCleaner. (or at least let them know what it was so that they can easily find your registration).

@SteveTK As I was getting to above if your internet wasn't connecting for some reason then both Speed and Security would be greyed out. If only one of them is greyed that would indicate an issue connecting to one particular server. If it's only just happened, and it wasn't greyed out for your before, then it's probably something at the server end. Maybe a connection glitch, maybe a server glitch, maybe just server maintenance. In either case it should connect if you try again later when the server is back online. (Which may be why the original poster didn't come back, his problem disappeared on it's own when the server came back online?) However if it remains greyed out for a day or two then that's probably your antivirus/firewall settings blocking the connection. If that's the case and you need to come back to use then please let us know your CCleaner version, your Windows version and build, and what Antivirus you are using and if it's not Windows Defender then the AV version. TBH in my opinion the Speed function doesn't really need running everytime that you run Health Check, but that's the way Health Check currently works. The Speed function clears/prevents unecessary apps from starting with your computer and thus slowing it down by running in the background, once cleared from the startup list these are unlikely to come back into it again. (Health Checks' Speed is the equivalent of Tools>Startup from the CCleaner menu, but in Health Check it is run automatically with it's own rules of what to remove from that list). The possible case for running Speed everytime with Health Check is if a newly installed/updated app, or Windows Update, has put something new in the startup list

As far as I can see those two files are identical apart from having different names. So if you are matching by size and content, but not by name, then they will be found as duplicates. If you only want to find files with the same name then you should match by name as well.

I seem to recall that in certain circumstances Thunderbird can link to Firefox and cause CCleaner to say Firefox is still open? I'm not at home at the moment, you could try the searchbox above to search these forums for 'Thunderbird' to see if you can find anything about it.

Just to be sure, do you have any extensions/addons that may be continuing in the background after Firefox is closed? Also, are you using Thunderbird for emails?
