since it only happened going from v4.10 to v4.11 and goes away when reverting back to v410, it would suggest a problem either with CC itself or the new version as somehow highlighted a problem with your PC.
the Dev team do read these posts so they should be aware of your incident.
another straw to clutch, have you booted to Safe Mode and ran CC there to see if it shuts down the PC when you tell it to do anything?
Have I violated 10? Didn't think I'd answered anything in this forum.
"since it only happened going from v4.10 to v4.11 and goes away when reverting back to v410, it would suggest a problem either with CC itself or the new version as somehow highlighted a problem with your PC."
Should I download a fresh copy of 11 and try again? Do I need to unistall 10 before installing 11?
"the Dev team do read these posts so they should be aware of your incident."
Good to know that the team watches the forum.
"another straw to clutch, have you booted to Safe Mode and ran CC there to see if it shuts down the PC when you tell it to do anything?"
Oops, oversight...Didn't try safe mode..
"and what AV do you run?"
Norton 360
Also have 3 IoBit programs = ASC 7 Pro Smart Defrag, & Malware Fighter
Thought about forum: user should be able to delete his/her replies
just to clarify Edward, I didn't mean clean using CC, I meant the whole nine yards, CC, DF, Malwarebytes Anti-Malware, ADWcleaner, and all those programs that scan for malware.
I mention Rule #10 not to suggest you did anything regarding that rule, but only to highlight that forum members aren't allowed to give advice regarding that aspect and to give you a place to start in scanning for malware.
For good measure, I would uninstall 10, reboot (yeah I know, shouldn't have to but, hey, we are up to the straw clutching phase) and reload 11. Make sure you get it from Piriform or FileHippo.
And since you are going to reinstall, do it from Safe Mode (to be sure, to be sure). And then do your first test in Safe Mode while your there and cross your fingers.
Again, I mention your AV as recently there was a issue with Avast and some users of CC, but this shouldn't be your issue. But if you try all the above and still have the problem, let's try disabling Nortons real-time protection for 10 minutes and see if that helps.
Yep and the Dev Team read all posts, but very rarely comment on any. If they ever need further info, that's when they'll chime in.
You may also want to look in your Windows Event Log by opening Event Viewer, hopefully it will have logged any issues/errors.
And just to make sure:
1. Open CCleaner from Start->Run and manually have it load CCleaner.exe (don't use a shortcut).
2. Go into Options->Advanced and make sure this box is not ticked: Shutdown after cleaning
3. Close CCleaner, then right click and select Properties for any CCleaner shortcuts you have on the Desktop, Start Menu, etc., and make sure the Target doesn't have any parameters listed after CCleaner.exe, in particular make sure it doesn't have /AUTO /SHUTDOWN listed in it:
Example 1 (CCleaner runs normally with manual user interaction):
"C:\Program Files\CCleaner\CCleaner.exe"
Example 2 (CCleaner runs automatically without any user interaction, and will automatically shutdown/turn off the computer when finished):

I clear the cache every few minutes using fiddler. I run all my maint programs at least daily in addition to the autoscans.
"For good measure, I would uninstall 10, reboot (yeah I know, shouldn't have to but, hey, we are up to the straw clutching phase) and reload 11. Make sure you get it from Piriform or FileHippo."
Used Filehippo to check for the update. Downloaded 11 using IDM to D;\program files\ccleaner)\. Used IObituninstaller to uninstall 10 asnd check for remnants. (kept 10 installer and 11 installer and items in doc&settiings).
"And since you are going to reinstall, do it from Safe Mode (to be sure, to be sure). And then do your first test in Safe Mode while your there and cross your fingers."
Rebooted 2x, 2ndtime to safemode. Installed 11 while in safemode. Ran CCleaner: seems to work fine here. Note: Norton does not run in safemode, at least not in the usual manner.
Will now reboot normal and see what happens. BRB
Have rebooted regular and seems to be OK now.
@Andavari
No parameters in shortcuts. I checked that when I was experiencing the issue, none then either.
Off topic question: Can I get "Scheduled Tasks" to auto run CCleaner every 2 hours rather than only at System startup?
This is just a suggestion since some time ago I experienced a similar problem that seemed to either be OS related or application related. It never occurred to me that it might be hardware related.
If your power supply is failing any additional input can cause your system to shut down due to low power output. I guess that’s a safety feature to prevent data corruption.
If you think it’s worth looking into there are relatively inexpensive power supply testers available at electronic stores.
