Antonia82 reviewed v5.55.7108 on Mar 27, 2019

Pros:

Cons: Well it was the telemetry and the overall quality problems it had in the latest versions. These forced updates and opt-out feature previews, I didn’t experience, but learning about it reinforces my decision. I hate the trend of software that does what it wants and not what the user wants, especially for security / privacy-oriented software, it makes no sense.

Bottom Line: Now switched to Cleanmgr+ from the old dev team of Xleaner

Pros: Junkwarw

Cons: Used to be good

Bottom Line: I stopped using CCleaner, I used to use it and recommend it to clients. I now use & recommend Bleachbit, which is an open source free cleaner.

Music4Ever reviewed v5.52.6967 on Jan 17, 2019

Pros: Used to be the best now no good points

Cons: Latest trick is for Avast to add cookies in CCleaner & then white-list them, this on a cleaning product - Dreadful behaviour from Avast who seem to have no decency or values & never learn either.

Bottom Line: Was the best now don't use it I am a pro customer until my licence runs out - At the moment it's blocked by my firewall - Use Wise, Clean Space or Privacy Eraser - No points.

JonIn92656 reviewed v5.52.6967 on Jan 17, 2019

Pros: Ccleaner was the best until Avast purchased it.

Cons: I downloaded the January 2019 update to Ccleaner and learned that Avast had installed their free anti-virus software. I did not ask for it, there was no notice that it was being installed, and I do not want this s*** on my computer. Avast has ruined what was once a great product.

Bottom Line: I will never purchase or use any Avast product. They suck!

Weilan reviewed v5.51.6939 on Dec 14, 2018

Pros: It's lightweight.

Cons: Contains malware from Avast that's constantly monitoring all computer activity.

Lacks thorough detection capabilities, it only scrapes the surface of what other junk cleaners can discover. It's always been like this. One had to install a plugin called CCEnhancer to boost its capabilities.

Bottom Line: It used to be good, but since Avast got it, they put their malware inside. It's constantly turning itself on, doing monitoring, who knows what else.

I switched to the Wise products.

some guy reviewed v5.50.6911 on Nov 30, 2018

kstev99 reviewed v5.50.6911 on Nov 29, 2018

Pros: Excellent Junk File Cleaning

Cons: Calls home constantly
Shady privacy policy

Bottom Line: I have used ccleaner for years, but since it was purchased by Avast, its questionable whether this program that is supposed to increase your privacy actually hurts it instead.

I even purchase the pro version about a year ago because of the nagging and wanted to support this program that I have used for years, but the annual subscription thing just plain sucks and I will not be renewing and am now using Wise Disk Cleaner instead.

I mean, what is the purpose of the app calling home when it doesn't even update itself? I have to read about an update on fileforum and then manually update. Sorry ccleaner but after my one year subscription expires I may keep an OLDER version on a flash drive for emergencies but that is it.

Joseph A reviewed v5.45.6611 on Aug 5, 2018

Pros: Very good cleaning!

Cons: Invasive and privacy behavior in the 5.45 version!

Bottom Line: Attention: Version 5.45 of CCleaner has been removed from its mother site! This version has been the subject of heavy criticism due to its invasive behavior and bad privacy policies.

Piriform has pulled back to version 5.44 and promised to improve on the above issues in future versions. The link to get the version 5.44 back is https://www.ccleaner.com/go/get_ccfree.
