My blog was hacked and a directory was placed on my server space. I am unable to delete this directory. When I do so, it says there is a script running. I am using Fireftp. I have tried to delete it from the web ftp and it does not work. It just says, "done", but it doesn't do anything. I've tried renaming the files and changing permissions, but that does not work.
Please tell me how to delete these files from my server so I can reinstall fresh and get everything going again.
