I uninstalled LW and looked in add/remove for others, but there were none. I did the search as you suggested and these files came up:
recycle bin\Limewire 4.12.6 (shortcut)
C:\Program Files\LimeWire (folder)
C:\Program Files\LimeWire\LimeWire 4.2.6 (folder)
C:\Program Files\LimeWire\LimeWire.jar (TMP file)
C:\Windows\Preftech\LIMEWIRE.EXE-1944953E.pf
C:\Windows\Preftech\LIMEWIREWIN-FULL.EXE-2F5F73A6.pf
C:\Windows\Preftech\LIMEWIREWIN.EXE-2673478F.pf
C:\Windows\Preftech\LIMEWIREWININSTALLER 1.EXE-000F94D8.pf
C:\Program Files\LimeWire\LimeWire 4.2.6\limewire.props
C:\Windows\Downloaded Installations\{303F45CA-471F-4585-BE59-8BCC13C79540}\LimeWire

What should I do with them?
