How did you uninstall? The right way is via start > all progs > LW > uninstall. Going through add/remove programs can cause problems. You could try reinstalling LW, then uninstalling the correct way

Can I just ask why you uninstalled LW? Was it popping up all the time & refusing to stay closed? If this was the case, usually uninstalling LW isn't enough... the virus remains & can cause these error messages to pop up after uninstall. If this sounds like your problem, see point 4 in the thread below. You'll find a link to Norbiesworld...go to the site & follow the directions for free computer help. Norbie can help to fix things up
