For almost 11 years (since late 2010), when you install or update the free version of CCleaner, there may be an offer for Chrome or some other software shown. Your assumption is correct - as we declare at the top of the display: CCleaner has quite a large free user base (we don't publish the numbers, but it's larger than the population of most countries) and this helps offset the costs so that we can keep CCleaner free available to everyone. They are marked as an "optional offer", there is no obligation to accept them, and you can certainly click the big blue "decline" button if you don't want it. If you are not a Chrome fan and want a web browser with an Ad Blocker and enhanced protection from tracking, you may prefer CCleaner Browser: https://www.ccleaner.com/ccleaner/browser

You will get occasional renewal reminders coming up to your expiry date with links to loyalty discounts and/or exclusive renewal offers. If there is a sale on, things get a little noisier for a couple of days. The current cashback promotion for renewing customers ends today, so you won't hear back about this one after the "last chance" message. Our cashback offers let us give much bigger effective discounts that we normally be able to provide. There are a couple of extra steps that you need to go through after the purchase, but we have tried to make the process and quick and straightforward as we can to get the rebate paid back to you. We have rebated over $1M to customers over our recent cashback campaigns - so we have the process down reasonably smoothly. The cashback is paid back as a rebate to the same method of payment that you use to place your order. If you purchase the 2 year CCleaner Premium / Kamo bundle (for up to 5 computers), you will receive a code along with the purchase that you can use to process your claim through a web form. You can find more information about how the cashback offer works by scrolling down to read more on the cashback webpage that you visited, and also on https://www.ccleaner.com/ccleaner/cashback/how and https://www.ccleaner.com/ccleaner/cashback/support. Some customers like the additional savings from the cashback, some prefer a straight discount. If the cashback process does not appeal to you, you may receive some form of straight discount offer (albeit with a smaller discount rate) at some point in the future before your licence expires.

Most of the larger brand antivirus software keep their whitelists up-to-date so that shouldn't have been a problem - although occasionally there can be issues when we release a new version and they are running behind. As per the help guide at https://support.piriform.com/hc/en-us/articles/204043844-How-to-register-and-activate-CCleaner-Professional, you can redownload CCleaner Professional from https://www.ccleaner.com/go/get_ccpro - or download the free version from the CCleaner website and register that. Note that you may need to register it again to unlock the Pro features - if you have lost your registration details, you can recover the from https://www.ccleaner.com/support/license-lookup. As always, the customer support team at support@ccleaner.com is always there to assist customers with a current licence, if you have trouble with the process.

@cchater: This sounds like a different topic to the free update reminders in the thread above. There are only two types of emails that are sent by CCleaner: our public newsletter (if you have signed up for it), and service notifications relating to paid subscriptions - ie: renewal reminders which will generally include some form of discount loyalty offer. Both of these will have an "unsubscribe" link down the bottom of the email if you do longer wish to receive them. There is also a billing reminder issued by Cleverbridge prior to annual subscription billing taking place. Note that paid licences include customer support - so while your licence is still active, if you are having difficulties using CCleaner and require assistance, you can contact customer support (support@ccleaner.com) with details and they will be more than happy to help.

If you are using CCleaner Professional or CCleaner Business Edition, note that those are unmanaged endpoint products and not designed for that sort of thing - as the assumption is that all of the devices would generally be in the one household or business premises. CCleaner Cloud is designed specifically for businesses with 10+ computers, or where some form of remote management is desired - and you should be able to see client usage information in the management console.

I am using CCleaner Browser v91 beta and I am seeing the Adblock counter ticket up as I browse through YouTube (and no ads displaying) so that looks promising on that front. Video downloader fixes still seems like a work in progress though.

Alas no - not yet. We extended CCleaner Professional Plus licensing to cover both PCs and Macs back in 2019, but we are still working on integrating the mobile licensing. It is coming - but not soon.

When you go to Custom Clean > Applications do you see Avira on the list under either Applications or Utilities? Are you using CCleaner's native cleaning rules, or have you plugged in additional external cleaning rules (eg: winapp2.ini).

Just checking: Was this the automatic update, or did you manually update from the website? Were these notifications after the 5.80 update had already been applied? Or did they prevent you from updating to 5.80?

Some games embed a web browser when they run, so closing the game may trigger the same behaviour as if you had closed a browser. What is your experience on closing one of these games vs closing a web browser? And to confirm, your settings under Options > Smart Cleaning are all off?

Do not post personal information on a public forum. Any requests relating to your CCleaner Professional subscription will be handled promptly by an email to support@ccleaner.com. If you are contacting support using an email address other than the one that you registered during your purchase, please be sure to include one or more of your licence key, your Cleverbridge order number and/or the email address that you originally used to purchase. Note that there are also self service options available. For example, checking your licenses can be done via https://www.ccleaner.com/support/license-lookup. Future subscription billing can be cancelled via Options > About > License Information > Manage Subscription inside the CCleaner product itself, or via a cancellation link that would be in your original purchase confirmation email, and also in the subscription billing reminder that you would receive from Cleverbridge approximately 2 weeks before anniversary billing occurs.

I gather that Microsoft's support for 64 bit applications on ARM devices is still a work in progress: https://www.techrepublic.com/article/windows-on-arm-this-is-how-well-64-bit-emulation-is-working/ - but I note that this is the 32 bit version that you are running. I'll see if support has had similar cases.

I believe that this case (and quite possibly the last one, if memory serves me) was not the accent but a change of name. CCleaner licence keys are hashed against the original registration name, so if you originally purchase as "John Smith" and then renew as "John R. Smith", the licence key will insist that you continue to use "John Smith".

Downloading is always free - it is the subscription that unlocks the Pro features that you need to pay for. If you ever need to reinstall CCleaner Professional (or put it only a new computer), you can get the link from here: https://support.piriform.com/hc/en-us/articles/204043844-How-to-register-and-activate-CCleaner-Professional or directly from https://www.ccleaner.com/go/get_ccpro. If you have Automatic Updates switched on (Options > Updates > Keep CCleaner updated automatically from the CCleaner console) then CCleaner will update itself within 12-36 hours of the new release being announced, or after you next restart CCleaner.

Slack is a popular team collaboration app, which has seen even more use in the past year from people working from home. It is similar in function to Microsoft Teams, but Slack as been around longer. We use it ourselves in CCleaner. And this new Slack cleaning rule just cleared a LOT of space.

If you purchase the CCleaner Professional Plus bundle there was a download link to the bundle installer (which downloads and installs all 4 utilities in one go) in your confirmation email, and also a link to the help article (https://support.piriform.com/hc/en-us/articles/360028350711-How-many-computers-can-I-install-CCleaner-Professional-Plus-on-) on where you download the all-in-one installer for PC (https://www.ccleaner.com/go/get_ccproplus) and the CCleaner Professional installer for Mac (https://www.ccleaner.com/go/get_ccmacpro).

This may have been mentioned in the renewal reminder email, but for additional information: Will I lose any time on my subscription if I take an offer to renew early? – Piriform Support

In your email purchase confirmation from Cleverbridge there should be the contact address for customer support - support@ccleaner.com. Note that this is a service for customers with an active paid licence, so is not widely publicised on the CCleaner website. If you contact them from the email address that you used to make your purchase then this will create a support ticket which will get a receipt confirmation, followed up by a personalised response. To save some time though, if you need to recover your licence registration information (key and registered name), you can visit https://support.piriform.com/ and click on the blue "Send me my license details" button to get these sent to you instantly. Also handy would be this guide to registering your licence key: https://support.piriform.com/hc/en-us/articles/204043844-How-to-register-and-activate-CCleaner-Professional. 9 times out of 10 the issue comes down to mistyping the licence key (usually entering the number "1" instead of the letter "i" or something similar). We strongly recommend copy-pasting the information from either the order confirmation email, or the licence details information you would receive from the licence lookup form.

This sounds suspiciously like what we used to call the "vendor salute": (ie: "blame someone else, usually Microsoft ) That said, I would note that versions of CCleaner prior to 5.46 are no longer compatible with Windows 10 release 1809 and above. Anything above that (generally recommended to be one of the 3 latest releases for compatibility with other software on your computer) should be just fine. Last time I had that error it was a hardware problem, consider: Chksdk for disk errors Checking for RAM problems (as per Andavari, above) Checking for out of date device drivers

To run with the metaphor ... A couple of driers "caught fire" and users erased more than they intended. Possibly the drier's fault ... or possibly they ran a butane bottle through the drier. As a temporary measure the "Wipe Free Space" option has been removed (as per the release notes), but will be restored in an upcoming release after investigations are complete.

The CCleaner community forum website has no information about billing (and, being a public website, is not a good place to publish any personal information relating to your account). While there is information about how to manage subscriptions in the help centre off the main CCleaner website (eg: About licenses and subscriptions – Piriform Support), subscription cancellation can be accomplished with a couple of clicks either from your licence information in the product console of CCleaner, from the link in your original order confirmation email from Cleverbridge, or from the billing reminder that Cleverbridge sends ~2 weeks prior to renewal billing taking place.

Piriform remains committed to CCleaner across the Windows, Android and Mac platforms. Indeed we have recently brought on additional developers to focus on the development of a major Mac release - CCleaner for Mac 2.0. (Expect to see a beta announcement in the coming months.) While the majority of CCleaner for Mac users are continuing to use it without incident on Catalina and BigSur, there are indications that a small percentage (<1%) of users seem to be having some issues relating to their individual system configurations - yes, they are having a problem. As with any other rarely-occurring issues with any software, in order for us to replicate and diagnose the nature of the issue we need feedback from impacted users with as much information as possible: product and OS versions being used, firewall and AV software that are on the computer, what system changes were made when the problems started, etc. While we are eager to help and to make our products useful to everyone, if we are given nothing to go on for investigations, attention is always going to be on developing the product to meet the needs of the majority of users.

@Nykk: If you have a question relating to your CCleaner subscription, as per your order confirmation email, you can contact CCleaner customer support at support@ccleaner.com. Edit: Although I note that you already seem to have done this, as customer support had already cancelled your subscription and issued a refund before you posted this message here. (... and for your safety and privacy, please do not post personal information in a public forum)

Needing to use task manager to close a notification seems a trifle excessive. Could you be more specific with regards to what reminders these are? Whether most notifications are displayed or not is configurable within CCleaner itself. And the notifications themselves would either have an X in the right-hand corner or a "no thanks", "remind me later", "skip to continue" or similar depending on whether it is a notification sent through windows, or a screen when you are in CCleaner itself. For example, the browser cleaning alerts will appear if you have set CCleaner to notify you when a browser has been closed so that you can select what action to take (or hit the X to close the window and do something about it next time). This is configured in Options > Smart Cleaning. Here you can see that I have to set to prompt to select what action to take for each browser. I can also set this to a number of other settings for each browser (to clean with or without notification, disable notification, etc)

We do seem to have the majority of our Mac users on the BigSur and CCmac 1.18.30 using it without major issues. Since the 11.1 bugfix patch from Apple, the most widely reported issue for CCmac 1.18.30 on BigSur is that Apple changed the version numbering prior to release and that CCleaner reports the OS Version as MacOS X 10.16. Also that some of the graphical elements have been resized by the OS and an issue with cookies on the latest Safari version. Are you able to provide any other information regarding your system configuration so that we can try to replicate your issue. Are you on a Mac using the new M1 chip? And specific firewall, AV or other system utilities that you are using?
