The normal process of uninstalling LW on windows is using the Start menu > Programs > LW > Uninstall. Using the add/remove control panel will not totally remove LW & may cause problems. For Linux however, I don't know how to uninstall it.

But then, I'm wondering why this thread was posted in the Gtk-Gnutella section since it's a totally different program.

BTW when the task manager fails, then points to a virus. Go to NorbiesWorld (click on link) & get him to help you clean your system.
