First try to delete in safe mode.
Be sure to go to an elevated command prompt and to use the good old dos commands to navigate to the folder and then use the DEL command.
If you can't delete, the folder use the attrib -r -s -h foldername /S command and then try to delete. If that doesn't work use DIR and then use attrib -r -s -h *.*. Now try to delete.
attrib -r -s -h 53ab78a8548aac7479d7a4ee /S
del *.* /s
You just be sure you are in the correct location before you use that del command.
If all of this doesn't work, then:
Make yourself a System Repair Disc.
Boot (you must actually boot) from the Disc.
At an elevated command prompt, now try to delete the files.
