Hmmm, I'd say your files could be gone and there might be nothing more you can do to get them back...As this is a fairly new virus we are in the dark about the causes and symtoms of it as well...
I must say that you need to be really careful with every download, make sure files are always over 2000KBs, do not download any zip, exe, wma, wmv files...Don't download any programs or games...It's just to dangerous...
Always Scan your file before playing it, you can do this by going to your shared folder outside of limewire (to find this folder click on one of your files in your LW library and click on explore)
That will open up your shared folder, now right click on your file and you will see the option to scan it with your AV and Spyware Scanner....
If you make this a habit you will stay safe...
