A hacker anonymously ftp into one of my machines and dump a bunch of
files. The directories have weird names so I went to the DOS promt
and I was able to get rid of most of the files and most of the
directories. The problem is a few of the files say "Access is denied"
when i try to delete them using del *.* /f. How can I make these
files accessible so I can delete them?
