Try deleting them with limewire shut completely down(not running in the taskbar). If that fails, reboot your computer and try deleting them in safe mode(keep hitting F8 while it reboots). The location of the file should be at C:\Documents and Settings\"your account name"\Shared.

If all that fails try this program: Download DelinvFile 3.01 Free Trial - Delete Invalid Files is a Windows program to Delete Files with Invalid names - Softpedia

Do you mean to delete limewire? Go to C:\Program Files\LimeWire\uninstall.exe, and double click to uninstall.
