CCleaner

CCCleaner professional. DON'T LET THESE SCAMMERS HAVE YOUR PAYMENT DETAILS.
Didn't want to renew, but money taken for renewal a month before the renewal date. Promised a refund, but then all you get is bombarded with "offers" to stay.
Looking at all the reviews it seems I'm not alone - there seems to be a definite pattern of extremely poor customer service & dodgy renewals, using Cleverbridge as an intermediary to help muddy the waters & delay refunds. You expect professional customer service from reputable companies these days, so I've been incredibly disappointed with their response. CANNOT RECOMMEND.

We used the extended version of their software. The hard drive immediately crashed and was destroyed and not recoverable.
We tried to contact CCleaner but they are not responding. It seems like this is a group of amateurs that I will never trust again with my PCS.
They seem non responsive and irresponsible too.

Ccleaner is the worst company I have ever dealt with. I paid over $20 to download their product. It did not work and I asked for help, then a refund. They have never responded to any of several emails direct to their so called support department and have not returned phone calls. They just don't care. Take the money and run.

I'm angry! I have the old free version, only sweeps cookies and stuff like that. Never upgraded because i have other soft ware doing the same thing. But ccleaner took a unauthorized withdrawl from me.
So difficult to get through to them, if they don't reverse the unauthorized withdrawl, i'm going to take legal action. Im sure it wont work but social media will be aware.

The startup Optimizer put all of my Office 365 apps into "sleep" mode, which resulted in not being able to start a word or excel document normally. I had to open them in admin mode. After excluding office from the optimize list, office applications could once again be run normally. I will not be using this "feature" of the program.

Have run this product successfully for years.

Made the mistake of "Upgrading" to the new version. New version suggested I put a number of programs to sleep, guaranteing that they would wake up when I needed them... Not so much.

So now I have a PC that Office apps no longer run on because they won't start. Piriform sold me Premium Tech Support. Only problem is that it doesn't exist. The support has always been marginal, but the product was good.

Now BOTH product and support suck.

I upgraded my ccleaner subscription to software that came with a vpn (kamo). All kinds of strange things were happening to my computer and I thought it was going to crash. After first reboot the new license key was vanished and it said I was using the free version. Anyway it was one thing after another and this 24/7 support they said I had was false and no one ever resolved anything so I requested a refund and asked for the old license key back when they ghosted me for awhile then sent me a key but refuse to extend the license for the three weeks that my computer was tripping out without the software that was originally paid for. Very dishonest ownership. BEWARE!

I am using Ccleaner 6.22 which I just received today, and Ccleaner is not cleaning Google Chrome. I used to have Ccleaner clean Google Chrome, but now Ccleaner 6.22 is not cleaning Google Chrome. I wanted to let some one know this.

Used CCleaner free for years with good service. Bought Professional, and a month before that expired they renewed it with an unauthorized credit card charge and NO nitification. I had NOT agreed to their "subscription". Trying to get this resolved is impossible based on their response. If they have your credit card information, they WILL use it and they tell you once they charge it, there are no refunds. BEWARE of this company.

I have twice tried using this product's "tune up" processes; once to update drivers, once because "my computer was feeling under the weather." Both times it totally disabled my computer. Once I had to take it to a professional to get it working again. The second I had to uninstall Chrome and Office 360 and re-install them. Probably have others I will need to reinstall. Also destroyed Quicken and I am having to re-enter months worth of data. I have not idea how this keeps getting positive reviews from the corporate reviewers, but I will never let it near a computer again.

I would give more stars except for the fact the program keeps popping up a window asking to upgrade to the Pro version even after the program is closed. This window has a no thanks option, but the fact that it keeps doing this id very annoying. Uninstalled because of this

I used it for My Windows computer cleaning, it's helpful with its efficient cleaning and maintenance of the computer, and it is useful to fix some registry errors and block phishing apps. But sometimes it becomes a time-consuming process and it is free with just some basic features, I need to pay for it...

I bought CCleaner some months ago. Cleaned my registry several times. Finally decided to clean my files also. When the screen came back I was unable to do anything. I had to do a hard shutdown. I was unable to get into Safe Mode. I called Microsoft and we determined that the registry was corrupt. We had to rebuild the operating system in place. I am still finding various functions that don't work but have been able to fix them. I would not install this software.

CC CLEANER WHEN I TRIED TO BUY THE ANNUAL €7.99 PRO PACKAGED FIRST TRIED TO SWITCH IT TO THE €28.99 PRO ULTIMATE SO I DID NOT CONTINUE WITH PAYMENT AND WENT BACK TO TRY IT AGAIN. IT THEN TRIED TO SAY MY PAYPAL PASSWORD WAS WRONG AND TO RESET IT. SO INSTEAD I WENT TO MY PSYPAL APP AND LOGGED OUT THEN LOGGED BACK IN WITH THE SAME PASSWORD I USED AND IT WORKED FINE. DO NOT USE CC CLEANER THEY ARE TRYING TO STEAL YOU PASSWORDS TO ONLINE PAYMENT METHODS!?
