From your post I assume you have already used START>Search>For Files and Folders.... to look for any remaining parts of the programs?!! If so and you have deleted those remaining parts after uninstralling via the usual way, that should it be acutually.
Next on the list would be to search for the " LimeWire" preference folder and delete it as well (look here under Point #2 & 3 in Fixes for Limewire on how to do this):

After you have done so, go and search for the LW/FW Incomplete and Shared Folder. Delete those both as well if still present.
Last but not least, if everything else is done yet the problem not solved, Open the Windows registry (but only if you're computer sawy) via Run...>regedit and go through the lists deleting all references for LW/FW.
But I actually believe that with applying the other steps beforehand, your problem should be solved by then before having to use the regedit option....
