I am sorry that did not work for you. I was having the same problem even when I totally shut off Norton and Windows defenses. I even uninstalled Li,ewire and reinstalled it three times as well as trying all of the other tricks that are posted and finally I decided to delete everything associated with limewire and updated my Java. I guess the last time was the charm for me. From what I have read it is affecting even those who have upgraded.

I thought this might help you as it did me, should I come across any other possible tricks I shall post them here to hopefully help you and others facing this pain in the neck of a problem.
