Try giving it at least 10% before you preview it...
Have you let one fully download and seen if it is ok ??
Another tip is to scan your files before playing them, you can do this by going to your shared folder outside of limewire to find this folder click on one of your files in the limewire library and click on explore....
Now just right click on the file and you will see the option to scan with your Antivirus...
I have made a shortcut to my desktop for my shared folder and that way I have easy access to the downloads and can scan everything as it finishes downloading....
