that's because the old antivirus doesn't uninstall correctly. Depending on the removal program you used that may be the problem. Is this the force uninstaller you used? http://www.pandasecurity.com/resources/tools/uninstaller.exe

In some cases after a forced uninstall, reinstalling, rebooting and uninstalling from Programs and Features solves the issue and restores the registry keys.

Also you may try restarting (if allowed) the Security Center as well as Windows Defender service. Make sure Windows Defender service is set to automatic.

In some cases malware prevents Windows Defender from starting. If you haven't don so already, run Malwarebytes and check the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options for MSASCui.exe, MpCmdRun.exe or MsMpEng.exe. If any of those are in the list, right click and delete. Close registry editor and reboot and try again.
