I went in to purchase the 30% off, 1-year subscription. The page automatically selects the yearly renewal, where you must physically cancel to stop them from a yearly re-charge of the full $24.99. So I un-clicked the box, and the agreement under the Submit button switched to where I was no longer agreeing to the yearly charge. BUT, when the page sent me to PayPal I was told in the fine print that I was allowing them to deduct a yearly charge, with no way of opting out! Thank goodness I re-read the terms on the PayPal page, I wonder how many people don't?
So, I called their customer service, which is not an easy phone number to find, and their answer was that I could simply cancel before the year was up. When I said no, I don't want to agree to it in the first place, THEY HUNG UP! I called back, got the exact same response from a different agent, they also hung up instead of explaining!
This is despicable behavior from a supposed security company who is supposed to be trustworthy. How can you possibly rely on their product when the company itself has such an astonishing lack of integrity?

To order and PAY and sign up, ON the PHONE, NO problem. NOW?
I changed my OS and there is NO WAY to contact CCleaner for HELP. I have a PROR level I PAID FOR.
DO NOT USE CCleaner. NO SUPPORT!

SLEAZY billing practices
September 13, 2023

They SLAM you with renewals and make it IMPOSSIBLE to undo auto-renewal. For that reason, ccleaner is now a -10 in my book. AVOID AT ALL COSTS.

I have been using this handy clean up utility software on my PC for years now. It does what it is supposed to do flawlessly. You can quickly and easily get rid of unnecessary junk that may be slowing down your computer, like temporary files, cookies, old registry files and so on. With a few simple clicks, all of your junk files will be wiped away. There is also a cellphone app version that will do the same thing for your phone. I have also been using the cellphone app version for a while and it is great, just like the PC one. You can choose to use either the free version or upgrade to the premium paid version for both your PC and cellphone. I have been using the paid version for both my PC and cellphone, so I can honestly say it is great and worth the small licensing fee you pay for them. The free version works just fine, if you don't care about or aren't interested in the little bonus perks of the paid version. Either way, you will be cleaning the junk out of your PC and cellphone with no effort at all.

I mainly use CCleaner as my Disk C cleaner on my Dell laptop. This small yet powerful program is a thorough system cleaner. It deeply scans your system and then lists a lot of items you can select to clean related to Windows system and third-party applications. You can wipe off a lot of things such as browser cache, temporary files, unused craps, cookies, logs. What is worth being mentioned is the plug-in "CCEnhancer". It adds extra cleaning rules to CCleaner to free up more disk space. I found that because CCEnhancer adds more options to clean, the program would load all scanned items slightly more slowly than before.

The paid-for upgrade to pro version brings you several more features including "Real-time Monitoring", "Scheduled Cleaning", "Automatic Updates" and "Premium Support". These are not quite useful for me but might be necessary to others.

In a whole, I think CCleaner is a great choice to clean trash when your computer gets clogged up.

Hands down one of the most thorough (and safest) cleaners I have used yet. You will be very delighted with this program. Also, stop by and pick up the free plug-in CCEnhancer which extends it's capabilities to cover over 500 additional applications at: http://thewebatom.net/software/ccenhancer/

I use my 2 favorite programs, ccleaner and defraggler, every day. I've never used a better defragmenter than defraggler. Ccleaner has no (free) equal either. If you need some simple, free software to tune your pc up, these are the guys. I can't believe there's only 1 other review here.

If you use ccleaner, take caution in the "advanced" deletion pane, because if you delete "old prefetch data", it will take a long time to load a program that hadn't been used for 2 weeks prior to deletion. NEVER delete old prefetch data. "old" doesn't make sense anyway.

Piriform is a great company with great software. Free disk defragmenter, free disk cleanup software, and others. I use the antispyware on ALL my computers. CCleaner will get rid of a lot of space junk that ends up on your hard drive - AND it will improve your computer's performance.

AWESOME.

Even the standard version frees up space helped me well. Usually free services are not very reliable, but they are great. Thank you

Ccleaner is one if not the best register cleaners i have seen. It cleans your registry and usually cleans a gigabyte off of my computer; i recommend it to be used and not any other one you might see!

I had to search this page out. I wanted to thank you for this wonderful program! I just ran it. I run it much. I am having problems with my computer. I spilled coffee on my keyboard and eventually it sopped working. Even though I am using A USB keyboard and have tried to uninstall my default key board my computer keeps reinstalling it. And I have problems with my password at boot. Well I am in windows now and I leave the Computer on for A long time. So I don't have to try and reget into windows. The computer messed up and I couldn't see my thumbnail pictures, as well as some other problems. I ran Ccleaner and they reappeared! I haven't checked the other problems yet but I
'm guessing they cleared up as wellas well. Now I may not have to restart my computer to fix the problem. I wish I could upgrade, I just can't afford to right now. But plan to when I can! I am still using the free version. Thankyou. Duane Schott.

WOW was I glad to get turned on to THIS website!

I'm sure you've all seen the advertisements (and the scams) about software that will "make your computer run faster" and they offer a "FREE SCAN". Then the nightmare begins, where they tell you that you have over 1,000 problems with your computer and then try to sell you their Registry Cleaning software package. Now, several of these are very good (PC Tools, AVG, Norton), BUT they all cost at least $29.95/year!

CCleaner.com is the best and ONLY totally FREE Registry Cleaning software out there. It's easy to use, does the job quickly and thoroughly and is ABSOLUTELY FREE (Gawd I sound like a commercial for them, but really I'm just a satisfied user). There's no reason to pay big $$$ to get this type of software.

Registry fragmenting is the leading cause of your computer slowing down with age. You have to clean it up (your basic "De-Fragment that comes with Windows doesn't do this), and you need software like this to do it!

Here's a youtube of a guy who will give you the info and a quick tutorial on how to use it:

http://www.youtube.com/watch?v=H-2VOMp7fvw

Then just go to www.CCleaner.com and get yours. My sister (a huge computer geek) turned me on to this after I got aggravated by the other companies trying to charge me for it (even AVG who I just paid $50 for the year of security software and why isn't this included anyway i asked?).

I'm amazed at how much faster my hard drive is running. This is a totally unbiased review, I only know enough about all of this to be dangerous. Even my website programmer told me that this is good stuff and have no fear. Anyway, here's to faster computers! Enjoy.
