I can open Opera Web Browser by Applications >> Internet >> Opera Web Browser.

I recently uninstalled Opera Web Browser. However, when I go Applications >> Internet, the Opera Web Browser is still there.

When I go into Main Menu >> Internet to delete it, there is no such item. However, when I open up Applications >> Internet, the launcher is still there.

When I click on it, it says Failed to execute child process "opera" (No such file or directory). How do I get rid of this in the menu?
