I installed an AdKiller extension on Google Chrome over a year ago. It's apparently malware. Not long after opening Chrome, but not immediately, I get a message stating that AdKiller has been removed, presumably by Norton, but I keep getting the same message whenever I reopen Chrome. When I look through the list of programs in the Windows 10 Uninstall area, I don't see any that contain AdKiller in its name. Does anyone know where this software is hiding and under what name so that I can permanently uninstall it? Thanks.
