If you've uninstalled LW but it's still trying to start up, you probably have a worm.

Have a look at the thread below, there are different fixes which have worked for different people.

Before you uninstalled LW, were you also having trouble getting into LW's tools > options? If so, the thread above also has a link to download AVG Free antivirus...this has helped with the options problem.
