Unknown Files

Recently, every time I use CCleaner Registry Cleaner I see a list of about 20 entries all with similar file names to the one example file listed below.

When I clear them by clicking on 'fix selected issues' and then 'scan for issues' again, it comes up with a second list of items as shown below.

When I click 'fix selected issues' the second time it clears everything.

This has never occurred before, it's always cleared any items in one go. Plus I have never seen so many items to clear, or of that description, and I wondered if anyone knows what program they are related to, or if they could be a problem? Thanks.
