Hi
Since I updated to the last free version of Ccleaner (6.34) each time I use it I have 3 popups of advertising (your pc is clean, you should start 60 days free blabla…, your pc is clean)
How to disable these popups I didnt get since years I use ccleaner?
Thanks for your help

I agree, far too much in house advertising for a program I have used on my computers for decades! I have a customer base that I maintain their computers. I nstalled CCleaner on every computer I have worked on for years. 90% of those computers have CCleaner uninstalled when I get them back in for repairs. EVERYONE one of them state that they removed it because of the POPUPS! Time to find a replacement! Any suggestions?

As you are using CCleaner in a business you will have priority support to contact with questions.
(You do have a business licence for CCleaner don’t you?)
No, I was using the free version as I installed it on my customers computer as a courtesy which was good advertising for CCleaner. Definitely not going to do that anymore and am looking for a replacement program for my computers.
HI @hazelnut The problem is not to have free version or professionnal licence.
Since the last version, each time with click on a button, we have (not only me) 4 times (4 TIMES !) the very big popups “your pc is clean blabla…” and another popup “you should try 90 days free trial”.
Everybody understand ccleaner want users to pay but these popups coming the middle of the screen are really TOO MUCH !
As @AnaRon asks, yes I’m thinking to create a powershell script to clean my pc

Hi web1:
Are you are referring to the series of pop-up ads like the ones shown below that appear after running a Custom Clean with CCleaner Free v6.3x? If so, I believe these are the same intrusive pop-up ads discussed in Jeff_M’s 01-Apr-2025 Screen flashes that can cause the CCleaner Free v6.33 and higher interface to flicker (i.e., temporarily turn grey) if these pop-up adds fail to render correctly after a Custom Clean.
I m guessing Avast / Piriform deliberately added this series of intrusive pop-up ads to try and push frustrated CCleaner Free users into purchasing a CCleaner Professional license. This is similar to the same aggressive tactic they used in June 2024 when they disabled the Custom Clean feature in CCleaner Free v6.24 without any warning, and then reversed their decision six weeks later and re-enabled Custom Clean after users expressed their anger and/or simply abandoned CCleaner Free and moved on to an alternate free disk cleaner - see the 100+ comments posted in Sectorgz’s 04-Jun-2024 CCleaner 6.24.11060 will not do a Custom Clean. Here’s hoping Avast / Piriform comes to their senses again and removes these annoying new pop-up ads before more users abandon their product.

Hi
This is the screens I get but i dont understand why Avast ?
Probably no solution if not a lot of users say smothing
Hi web1:
Avast acquired Piriform, the original developers of CCleaner, in July 2017. In my opinion, the quality of CCleaner, along with its customer service, has been on a steady decline since then.
Norton LifeLock merged with Avast in 2022 to form a new company called Gen Digital. Several brands like Norton LifeLock, Avast, AVG, Avira, and all the products previously developed by Piriform (including CCleaner, Recuva, Speccy and Defraggler) are now under the umbrella of Gen Digital.
Gen Digital is also sharing all sorts of technology between their subsidiary companies and don’t even try to hide it. For example, CCleaner users who have never installed a Norton product are now finding Norton folders on their system, and Norton users are finding traces of Avast on their system. See my post # 2674772 in Specialist17’s 24-May-2024 Norton Security now silently installs Avast software? in the AskWoody forum for further details.

In my eyes it would be a bigger issuse if they were trying to hide it.
‘Sibling’ companies in the same group share resources, they always have done and always will do.
Why spend time and money developing something for your company when your ‘sibling’ company already has it and will share it with you?
The annoying bit to me is that the recipients don’t spend the time to check and clean up what they have been given, they just use it ‘as is’.
That’s where those Norton folders that CCleaner created came from - they were created by the borrowed Norton code snippet for use later on in the programme that the snippet came from, CCleaner does not use them at all and so the code that creates them could have been stripped out before it was merged into CCleaner.
It’s a leftover/not-needed bit of code and not to stip it out as being junk is simply lazy programme development.
Hi nukcade:
Sloppy programming aside, my own objection is with all the unnecessary, buggy bloat (e.g., Driver Updater, Performance Optimizer, etc.) that’s been ported over to CCleaner from other Gen Digital products since Piriform was acquired by Avast in 2017.
Getting back to the topic of this thread:
Having to click a monthly “No Thanks” link on a system tray pop-up ad after each CCleaner Free version release is one thing, but the intrusive pop-up ads shown <above> that now appear after every Custom Clean certainly aren’t helping to improve anyone’s opinion of this product. These new pop-up ads are so annoying that they’re probably having the opposite effect of what Gen Digital was hoping for - namely, selling more Pro licenses - and driving users like me away from CCleaner.

On the machine where I run CCleaner Free I only see that particular pop-up about every six months, and although I do see others they are not excessive.
One thing that I have noticed over the years is that people who block CCleaner/Avast in their firewalls seem to get many more pop-ups than those who don’t.
My own belief is that happens because the pop-up server tries to query your machine to see when you were last shown a particular pop-up.
If it was less than XX number of days then it won’t serve it up again until XX days have passed.
However if it can’t get an answer, because your firewalls are blocking it, then it will just assume that it hasn’t been shown already so will show it everytime it can’t get an answer.
PS. I agree that all the added updaters, optimisers, etc. are unnecessary bloat. But they are there now and won’t be going away. Just ignore them.
i think “nukecad” might have identified the problem when he said that it seems that the people who have problems with the “ccleaner” popup messages are the ones who have “ccleaner” blocked from accessing the internet, and so “ccleaner” isn’t aware that they have already seen the ccleaner popup messages, and so ccleaner keep showing them over and over again.
Hi @lmacri Thanks for your answer and informations.
This is the screens I seen several times each time I use ccleaner
Very interesting to know its the same company of Avast…
I have Avast prmium and aleaner installed on my pc since years and this problem appaers only since the last version of ccleaner
i cheked online to find another cleaner tool but I dont know wich one to choose right now
Hi @nukecad you are right. When i look at the Avast cleaner tool ($70 by year…) I see exactly the same tool like ccleaner.
i dont’t have any norton folder
It’s the same when I block or not block in the firewall
the big problem is : if I open ccleaner 3, 4, 5 times in the same day, I will get each time these popups.
Hi @redwolfe_98 it’s the same when it’s blocked by the firewall and not blocked
Hi nukecad:
You might be correct - at least in part. I reset my Microsoft Defender Firewall on 15-May-2025 to remove my custom blocks for CCleaner64.exe and since then I’ve only seen the large pop-ups that cover most of the CCleaner interface (see the images in my 02-May-2025 post <above>) appear once after a Custom Clean. I’ve been running daily tests, and since that initial appearance of the full pop-ups I’m now seeing that odd “flash” where the entire CCleaner interface briefly turns grey after each Custom Clean that occurs in lieu of the pop-ups (see Jeff_M’s 01-Apr-2025 Screen flashes).
Unfortunately, removing my custom firewall blocks did nothing to decrease frequency of the intermittent pop-ups from my system tray that seem to appear about every third or fourth launch of my CCleaner Free Portable. Here’s today’s latest nag:
For now, my custom blocks for CCleaner64.exe are going back in my firewall, and going forward I’ll only be using CCleaner Free for testing (e.g., running comparative tests with other disk cleaners to see if they are more/less aggressive than CCleaner).

Hi web1:
A bit off-topic but you might be interested in reading about the CVE-2024-13944 security vulnerability reported 09-May-2025. So far this vulnerability has been confirmed for Avast CleanUp and Norton Utilities Ultimate (yet another example of code sharing amongst Gen Digital products) but I have no idea if CCleaner is also affected.
Kudos to SoulAsylum for posting about this in their 15-May-2025 topic Norton Utilities Ultimate / Avast Clean-up / AVG Tune-up CVE-2024-13944 in the Norton Tech Outpost board.

I see those lower right corner popups. Annoying , but easily closed.
if you unpin (thumbtack) the next notification you get, the popups will fade on a few seconds
