It's not only on his PC. 

 

Mine never does, except if I keep something open... eg Chrome

 

Edit

and an explanation to the Edge issue is here. But it clearly states this will occur only if a different program is accessing the Edge database

I use it often and it is one of the tools I use with my clients. Never seen this message.

Over the years there have been a lot of discussions in here regarding what ccleaner does, it's sort of mythical.  If you really want to get it it straight, read up on what the product does re Piriform rather than other people's anecdotes.

The beauty of the program, IMO, is that it can be tailored to remove (or not remove) particular things.  From within the program go to Options -> Include and work from there.  I'll run the file cleanup maybe once a week.

Briefly, a few myths dispelled:

  ccleaner is not an antivirus program

  nor an anti-malware program

  nor an uninstaller program

  nor a performance optimizer

 

Ok, there is a registry optimizer in there and I run it as is, meaning I've never put any effort into configuring this part of the program.  I'm not even sure if you can fine-tune the include/exclude registry data.

 

I usually do a big cleanup at least once a month (after the Windows updates), and when I do I'll run the ccleaner registry tool as well as the Glary registry tool, and the Glary picks up a lot more that the other. 

I've learned the hard way to never do a registry clean before backing up.  Registry compactors are something I avoid.

You can do all the cleaning via PC Settings/System/Storage.

 

Any malware/viruses should have been caught by Defender.

 

Glary Utilities gets good reviews.

But doesn't clean up the registry.  CC Cleaner does this but it can be aggressively dangerous.

Almost every time I use CC Cleaner

I use CCleaner, never tried CC Cleaner. Perhaps try an install of latest version of CCleaner - never get any issues with that.

What do you mean aggressively dangerous?

CCleaner attempts to figure out what items in the registry can be removed.   It is very likely to find hundreds of items to remove.  You are given the option to select what you want to delete.  Unfortunately, unless you are a true Windows geek, you will not know what these items are used for.  If you remove he wrong things, some things will not work anymore.  Or in one case for me, nothing worked and I had to resort to a complete system restore.  There is an option to create a recovery file to fix things but if you cannot boot, the file won't help.

Good advice, thanks.

Possibly useful for making a back-up of your Registry in the case of Registry infecting malware. But on a day to day basis, leave it alone.

 

Make use of a Sandbox when testing out new software. If all ok, then you can install it proper.

CCleaner does its job, but it comes with a price; They're collecting user data like most 'free'ware.

I've suspected this, but never put any effort into actual proof.  Instead I block it in the firewall and added an entry to the hosts file.

My experience is just the opposite.  Cc's registry scan will return a few keys suggested to remove, while Glary's registry tool will return many more, particularly after a Win Update.
