Next to my Malwarebytes shortcut icon it says sync pending, excluded from sync pending

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.

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?
