CCleaner used to run fast - now it is extremely slowly.

CCleaner for Windows CCleaner Windows Bug Reporting

I think CCLeaner runs extremely slowly. It used to run and close down in a few seconds. Now it takes forever. For example:

today I did an analysis before running the actual cleaner (something I never do). It took 2 minutes and 4 seconds to clean ~18 MB of files while set at "Secure file deletion (slower) Simple overwrite (1 pass)". Doesn't that seem excessive for such a small amount of data?

If you use winapp2.ini and/or CCEnhancer remove them first to see if it speeds up CCleaner.

Also according to the screenshot IE had 1475 files and since most installed antivirus will scan everything that CCleaner is removing and coupling that along with any secure deletion mode can equal a time penalty.

Also overwrite slows the cleanings. Your analysis shows (only) 0.814 secs.

You are running 5 months old version so I'd recommend to update to the latest CCleaner version (v3.28.1913).

Actually the screenshot shows an analysis of 167.1 MB

Why was only 18 MB cleaned.

Since you have not updated CCleaner for 5 months there must be a change in your system.

Perhaps a new anti-malware system that interferes with CCleaner actions

Perhaps a virus infection that is restricting performance - and also doing far worse things than slowing down CCleaner.

All good points. I will try to fix the issues noted above and get more data. I'll let you know what I find. 1st step update CCleaner...

Thanks all.

I wonder if you untick the cleaning of McAfee Antivirus if that could improve your speed. I know some antivirus software dislikes anything deleting logs, etc. But then again after I just did a 1-pass secure deletion of VLCPortable ("VLC Media Player Portable") it took a long time to get rid of it, so the amount of files, the file size, etc., could cause the slowdown.

Well I first updated to the latest version. That didn't fix it. Then I turned off the 1 pass secure deletion. That made a world of difference: cleaning 300 MB took seconds instead of minutes.

The question is: "How clean is clean without any overwrite?" Would it be a simple matter to undelete all of the files that appear to be deleted?

without overwrite it's like pressing SHIFT+DELETE

which is fine for what ccleaner's main goal is:junk cleaning

if you want secure you have to deal with the extra time it takes to, well, securely wipe.

Thanks Nergal. That's what needed to know.
