After IObit release Toolbox, I decide to use it instead of CCleaner, freeware the same but more tools to use for your computer 😀


this little app is lovely..useing it from years

Very basic. Good for beginners. Does not compare with TuneUp Ultimate or jv16

Thanks. Easy to use freeware!


This is a must have! Congratulations to the authors.


I love the prog like everyone else, but im telling you its still buggy,

the main reason is they are still supporting to many oses at once. 32bit, xp and 7, they should realise now is the time to finally drop support for xp.

they have an email from me, time will tel.


Big problem for me, i see that after using it firefox becomes very laggy, it blokes sometimes, scrooll almost suks, don’t know the cause momentarly but it only hapens after using ccleaner.


Thank a lot, it’s a MUST-HAVE.


I have used it since the 1st day it became available. One the best, if not the very best free program available for a very long time. The registry cleaner is one of the best of the free and paid version out there also.


Its Amazing software. Nothing Like CCleaner


CCleaner is only average I use SlimCleaner  and Reg Organizer are that much more thorough.


Cyberber , beginner …
now I saw your comment because I do not come here for a long time.
jv16 is important and effective like beta or final version. It is an app just for who knows and understands.
Your CCleaner, for me is soft of lazy or coward, who does not want to be risking anything to learn more . Keep your CCleaner . I prefer to pay by Tuneup, jv16 or, to use the CCleaner, a tool crap!

Will study IT ! lol


I agree with Arsenalz opinion on jv16 PowerTools. TuneUp Utilities…NO!! I don’t like their registry cleaner. It can screw up your OS big time. For a great registry tool, I use Advanced System Optimizer. I also use Registry Mechanic. Both are excellent reg tools and will not mess up the registry like so many others do. As far as CC goes, I’m not a big fan of this software. It’s okay but that’s about it, IMO..


I have just installed the new version over previous Business Edition i had installed & the program has stayed registered!! nothing else required


“- Added Windows Explorer Context Menu management to Startup tool.” This was already expected, great! ♥


ignore those noobs…who even think that ccleaner is not good..mercy on their stupid tiny brain lol
CCleaner the best freware tool..A MUST HAVE..nothing more have to say as everyone knows it..Ccleaner app is used my millions of millions worldwide because of its great quality..
And for registry cleaning you can use some other registry app


@ KenEzthex

I don´t agree but i respect your free choice, CCleaner still the best, i also use WinASO.


Muito fraco. Bom apenas para inciantes.

(Very weak. Good only for beginners.)


one of the fastest & best freeware cleaner…Its so safest that anyone can use it without any thought of backing up registry…nor it will mess up your pc or any app settings like what other so called cleaners do with the system and we have to take lot of precautions while using those apps but not in ccleaner case..
I think i am using it from 5/4 yrs just lovin it !
this app is not for those moron who have habbit of screwing/messing their PC, for them there’s TuneUp like things.


TuneUp Utilities, Glary Utilities PRO, Windows 7 Manager and System Mechanic Pro, are only for those who know how to use. For those who find difficult or are a beginner, I recommend CCleaner. hehehehe …


Self-proclaimed software user/looser nature will never change (thats their crap knowledge of understanding anthying)…they such a dumb that he even dont know the meaning of a freeware junk cleaning (portable) app ccleaner is ?? and comparing it with blotware big mb file size shareware..System Mechanic hahaha oldy a$$ still using old flop dead apps.
There’s an small addon CCEnhancer, which adds support/power for cleaning junk files from 1000 additional applications


agree and whos barking in many topic with his old a$$ dead apps seen clearly 😉
And again hehehehe…. like roadside pr0stitue giggling while seeing her customers… hahahahha


looks good


Very good tool…
Cleans a lot of trash and conflicts…


You can no longer download this anti-tracking software unless you enable tracking on their page. A contradiction. just hangs. Pity they do not allow other sites to host the software. Maybe they went rogue ?


arsenalz epa vai dar banho ao cão o TuneUp é que é para meninos. Meninos como tu que usam WinBLOWS. Os verdadeiros Geeks usam Linux e fazem as coisas “à unha”, tu és um “mero user” que usa windows ahahaha e que veio aqui mandar uns bitates. Enfim LOL


A totally useless program for windows


“CCleaner: 2m users install anti-malware program … that contains malware”

More than two million users of anti-malware tool CCleaner installed a version of the software that had been hacked to include malware, the app’s developer confirmed on Monday.

Piriform, the developer of CCleaner now owned by security firm Avast, says that its download servers were compromised at some point between 15 August, when it released version v5.33.6162 of the software, and 12 September, when it updated the servers with a new version.


“CCleaner Infection More Severe Than Thought, Targeted Microsoft, Google, Samsung”

[T]he server logs indicated 20 machines in a total of 8 organizations to which the 2nd stage payload was sent, but given that the logs were only collected for little over three days, the actual number of computers that received the 2nd stage payload was likely at least in the order of hundreds. This is a change from our previous statement, in which we said that to the best of our knowledge, the 2nd stage payload never delivered.
