Same here (link to my post):

Next time it happens, try to uncheck "Wipe Alternate Data Streams" in the Options/Settings. Cleaner will ignore the corrupted file and will be able to finish its job.
I have a sneaking suspicion that Cleaner corrupted the file in the first place in attempt to remove it. So, as a precaution, I don't use "Wipe ADS" anymore.
A word to the developers, if I may... Would you please take a closer look at this "wipe ADS" business? Something funny's going on there, and it ain't even funny (pun was intended), otherwise, it's a great product. Love it!
