If this is happening on Win10 perhaps that's the culprit after an OS update. One clue in that is the inability to save things like screenshots on the desktop.

CCleaner has never allowed wildcards for deleting registry data.

It's been discussed on the forums elsewhere before that if someone knows what they're doing with some layered security even old XP isn't as unsafe as some would try to make us believe. The problem with it however is the lack of new web browser support, and that some websites won't let you use them if the OS is XP, no proper support for modern SSD's since it doesn't support the Trim command, etc. It was however surprising that Mozilla seemingly pulled the plug several versions earlier than people were led to believe in Firefox ESR.

No. They make overly complex closed-source bug ridden software & OSes that's obviously a chore for them to bug fix and patch security holes in -- and we're the test subjects, and we pay for it as the OS price is baked into a new PC price.

Which is undoubtedly already inside the OS.

See here, then all the way at the bottom of the page there's related resources regarding a power supply making a buzzing sound: http://www.tomshardware.com/forum/355146-28-buzzing-sound-coming-recently-built As for the audio jack for the speakers, that can possibly happen due to static, or some other interference, etc. In the past I've had to unplug a 2.1 speaker system with a powered sub-woofer that was for my HDTV from the electrical outlet and plug it back in to stop the buzzing sound, eventually it became so annoying and loud I just replaced that speaker system.

That thing seriously needs to be discontinued, probably everyone hates it.

First guess = Power Supply Second guess = Speakers, especially if a powered sub-woofer is plugged in which could have static build-up over time, simply unplug it from the back of the PC clean the plug with an anti-static wipe, allow to dry, and reinsert. Seems to get allot of search engine hits with allot of people having the issue: https://duckduckgo.com/?q=powered+off+PC+buzzing+noise

Why make this more difficult than it needs to be? You should really abandon trying to use Recuva in this venture... ...in my opinion. Let's make this easy and try what you're wanting to do with CCleaner by wiping the free space on the hard disk (if it's an SSD completely ignore these instructions): 1. Open CCleaner. In the Windows (tab) scroll down to 'Windows Explorer', right-click 'Thumbnail Cache' and select 'Clean Thumbnail Cache' 2. Still in CCleaner, now go into 'Tools > Drive Wiper', and select 'Free Space Only', 'Simple Overwrite (1 pass)', tick the hard disk, and then click the Wipe button. Note: Depending upon the hard disk size this can take hours to complete. 3. After CCleaner finishes restart the computer. 4. After the computer has started open Recuva to verify wiping the free space worked.

See if setting CCleaner back to the default settings will stop it from causing the issue: 1. Open CCleaner. 2. Click: Options > Advanced > Restore default settings

Doing that with installed software in Windows could very easily break something. However you could always ask the developer of a program on their forums if it's possible without breaking the program.

I never had an issue with it and Firefox because it would only rarely compact the Sqlite database.

Firewall!

Thought that was interesting in Hazelnut's link in the above post since a very popular freeware Chinese antivirus copies stuff in System Volume Information, and uninstalling it doesn't get rid of it and neither does having System Restore delete all restore points (takes a Linux distro to remove the leftovers).

Should be safe! It's never caused me any problems with Firefox (or browsers based on it), and no problems with Chrome/Chromium based browsers. The cleaning it does in Firefox was, and may still be a command you could run yourself inside of Firefox, it's just far more convenient to have a cleaning program automatically do it without messing with a long line of code. Thing is unlike SpeedyFox it won't compact the databases ("Sqlite") files every time you run CCleaner, it does it on its own whim and time.

You'd likely also need to run the Avast Uninstall Utility to make sure "as much as possible of it is removed" from the system. Edit: Also see this topic about it not wanting to uninstall: https://forum.piriform.com/topic/52852-avast-uninstall-does-not-work-after-unrequested-install-by-ccleaner/ The way to avoid it is to start using the Slim Build or Portable ZIP both of which are available at: https://www.ccleaner.com/ccleaner/builds

The only work around that I know of would be to keep the settings separate from each other. I.e. treat each as a separate install/portable version as if it they were being used on different computers where you definitely wouldn't want to mix the settings, etc.

It does that on my Win10 laptop, just shows 16 GB.

It's had issues installing for many people for at least 2 or 3 years at this point, starting happening when they changed someting in the installer. Besides that, I think the easiest way to fix this for yourself will require some manual intervention on your part. Try this: 1. Install that older version that you currently have that installs without issue (if you've already removed it). 2. Make sure CCleaner is not running in the background, open Task Manager and kill any of it's running processes. This will be required for step 4 listed below. 3. Go here and download the Portable ZIP version: https://www.ccleaner.com/ccleaner/builds 4. Unzip the Portable ZIP version into the folder where CCleaner is installed, select Yes to Overwrite the files -- Note: This may or will require Administrator rights to overwrite the files! 5. Open the CCleaner folder, and make certain that you delete the following file: Portable.dat 6. Open CCleaner to make sure it with start without issue.

With how prevalent malware is you'd think a company owned by an antivirus/antimalware company would've known that, maybe not.

Working Example, just copy in the full path to your profile folder (doesn't matter if it's the installed version, or a portable version): CustomLocation1=CHROME|C:\PortableApps\IronPortable\Profile

I think it would be less confusing if offers like that were only shown in the main program GUI, then people would know for sure it's legitimate and exactly where it's coming from.

See this topic about install issues, there's some workarounds in it that may help: https://forum.piriform.com/topic/5739-solution-when-ccleaner-wont-install-or-download-windows/

Make a screenshot of it if possible and post it in here. Malware, maybe not, they do have some popup advertisements now that are annoying people.

I answered it in that original topic.
