What does this mean?
What section of CCleaner are you seeing this?
On the shortcut icon
I’ve moved this thread into the computer help section.
This appears to be a Microsoft OneDrive issue and nothing to do with CCleaner.
I suggest that you try a Microsoft help forum.
To start you of though:
What has Malwarebytes to do with OneDrive sync?
No idea, you’d have to ask MS why they are syncing Malwarebytes files.
I suspect it may be the scan logs though, and One Drive can’t sync them because they are open or protected?
