You need to run a chkdsk (or scan disk as it was called in the pre Windows XP age) as the file system somehow got screwed up. Go to start menu and go to "Run" (or "Search" if you have Windows 7 without the run menu visible). Type CMD. Press enter. You should see it pop up. If you do have a "Run" option in the menu, then it will start immediately.
You should then see a black box pop up with text in it. Type in "CHKDSK C: /F" (no quotes) into the command prompt. It will say it can't check because windows is running. When it asks if it can start the scan during windows start up. Tell it yes. Then restart the computer. It will then run the disk scan and fix the problem. It will either remove the corrupted folder or the files inside it. If the folder is still there when windows boots up, it should then be deletable.
