[Deletes MS Office 365]

Thanks for replying nukecad, no they are greyed out with no ticks 

[Deletes MS Office 365]

Dave CCleaner: Applications show both Office 2013 and Office 2016, both are unticked. However, I suspect that you are right it is the Start Menu and Desktop shortcuts that are disappearing which means that I have to re-install to get them back. Whether it is actually CCleaner which is the cause or not, I cannot prove. The EasyClean doesn't have this effect, just the Custom Clean.
 

Thanks to all for your replies and help.

If I use Easyclean then all appears to go well, however if I use the main CCleaner, it deletes Office 365 which I have to re-install. Any ideas why this happens please?

Thanks for all replies. It seems to have cleared the problem itself, I'm not sure what was happening but if it occurs again then I will follow your advice. Cheers now.

I use Webroot Secure Anywhere as my AV which Windows Defender has accepted. I am not sure why Webroot would suddenly decide CCleaner was malware just because I had updated Windows 10 though.

[Windows 10 v1803 - CCleaner removes itself?]

Since updating to Windows Home v1803 I find that after running CCleaner v5.43.6522 (64-bit), when I next go to CClean it has actually been removed. The shortcuts state that there is no program to run and I have to go to my Download folder to re-install.
Any ideas on what has caused this and is there a fix please?

have you ruled out the obvious suspects; PC in use?, background activity?, more space to wipe compared to last run?,  any scheduled events (eg: AV software scans)?, any automated events (eg: Windows updates)?

just throwing ideas out there...

 

try doing a wipe with the PC in Safe Mode and the ethernet/wifi disabled.

Thanks, I'll do a Sherlock Holmes at least knowing what I should be looking for.

My first 'wipe free space' took around 9 hours, which was fine. Now it seems to increase the time it takes each time... it is now 25 hours. I realise that on a 1TB drive with 845GB free space that even on low-level setting (used through 'Tools') it will take time, but why is the time increasing on each use?
