Download Unlocker 1.8.5 which will enable you to delete it without going into safe mode.
I use that program, too.
However, sometimes even Unlocker can't delete things, either.
Sometimes Windows blocks any access to particular files or folders, with its security settings.
You can access them by going into safe mode, and logging into the Administrator account.
Then, right click on the file/folder, and go to "sharing and security"
in the security tab, you need to go into the advanced options, and replace ownership of the file/folder.
