Cannot delete Linux files/folders

Hello, I'm having trouble deleting some Linux files found on an NTFS external HD. It's a .teamviewer folder that contains ...\dosdevices\c: (the "c:" appears as a file in Windows, but cannot be accessed/right-clicked etc). and another file that contains : in the file name. Unlocker won't delete them. Anything else I can try before using a Live CD? Thanks.
