Ran File Cleaner in lastest version. It developed an endless loop once I had selected files for deletion that it could not access. It kept trying to delete them and telling me it could not access them.
I had to abort, then uncheck the affected files before it would complete deletions without going into an endless loop.
Normally it just tells me it cannot access certain files (daily temp files from firewall and the name changes daily) because they are in use. It then stops on it's on and I will then uncheck the affected files and tell it to delete all others.
Basically same problem that siliconman01 had with the registry cleaner.
Now go have a great day.
