After running CCleaner 512, PC shuts down (WinXP SP3)

[LadyGuru]

I've never encountered a problem with CCleaner in all the years I have been running it on Windows XP. This is the first time this has happened. I thought it might be malware as something disabled my free AVG last week, but nothing is showing up on every type of malware scan I can run. So I've uninstalled CCleaner v 512 because I was going to update it to the latest version and while the program was going out to the internet to the website for the update, CCleaner was analysing and then cleaning my files and shut down my PC before I could update it. So I'm going to download and install version 514 and see if I still have the PC shut down issue. I will come right back and post my results. I thought you should know about the PC shutting down with CCleaner version 512.

I had done a complete uninstall of CCleaner v512 using Revo Uninstaller in case there was malware clinging to any of the registry keys associated with CCleaner. I did that in SafeMode and downloaded the latest version of CCleaner which was version 514, installed it and ran it in SafeMode. Then I rebooted the computer and ran CCleaner again (Analyze and Run Cleaner) and this time, it did not shut down my computer. So...it would appear that the issue is resolved.

 

However, there was an issue with version 512 shutting down my PC and like I said, I could not find anything to indicate there is any malware aboard my system. I run all of the best recommended diagnostic software for malware out there to make sure that I don't miss some of the most difficult to trace spyware, malware and viruses, including PUPs, rookit infections etc. particularly since Microsoft doesn't support XP anymore.

 

Have any other XP users had this issue? I noticed one user in a pinned post with SP2 had an issue similar with version 509, but theirs was restarting their computer, not just shutting down. My issue was happening for weeks. CCleaner had been shutting my computer down and I could not identify why it was shutting it down or what was the cause of it shutting down by itself until today.  I thought you should know. Cheers!

You may have had the following setting enabled which would explain the shutdown after cleaning:

Options > Advanced > Shutdown after cleaning

 

Or you may have had a CCleaner shortcut with /AUTO /SHUTDOWN in it from the command-line parameters.

 

And it will do just that, immediately shutdown after cleaning without giving you any notification or opportunity to cancel it.

 

Edit:

I'm also an XP user, and haven't had any such issues.

Had a similar post (not CCleaner) on another forum last week.

His was shutting down 'randomly'.

Turned out to be a backup programme, running in the background, that he had set to start on boot and shut down after completion.
