I used the Uninstall that came with the download. I uninstalled it because I got 2 trojans in a row shortly after downloading and starting to use it. I continue to get them since uninstalling as well. I had no problems with this prior to downloading LimeWire. I also was unable to exit from the program. It kept restarting on it's own.

LimeWire is no longer listed anywhere in my files that I can find, but it continues to look like it's trying to start & almost immediately after, gives me the error message in the first message of this thread.
