I have the same problem on my server with some files that were uploaded via WordPress. The solution is to use a web-based program to navigate through your file system and delete the unwanted file(s), because this would actually be apache doing the work, so it has the proper permissions.
Many web host providers have a web-based account maintenance utility available, so I suggest checking there first. If they don't, then your only alternative is to write your own or download one. Maybe check those free script web sites, and search on "file maintenance" or "site maintenance".
(I'm gonna write my own one of these days.)
