Windows Defender automatically disables itself when it detects that a third-party antivirus program has been installed, and as long as it thinks the other program is running you won’t be able to enable it. The removal process usually completes just fine, but occasionally just enough traces of the deleted program will remain behind to trick Windows Defender into thinking it’s still installed. Rick’s answer: Ellis, this is a fairly common issue when removing antivirus programs. I uninstalled it from my computer last night and now I can’t get Windows Defender to start up. Is there something else I need to do besides just uninstalling the Emsisoft program? Question from Ellis: My friend talked me into installing the trial version of Emsisoft Internet Security and I ended up not liking it.
