CCleaner stalls

CCleaner v3.0 on W7 stalls on "C\user\owner\appdata\local\babaus01-1.wav".

This has happened on previous versions and files. Sometime I can go to the file and delete, other times I have to do a system restore to a point before the file was stored.

I can't get to this file to delete.

Would like any help on this.
