Windows 10: Windows defender realtime protection

Activate realtime protection on windows defender an cloud delivered

Windows Defender realtime scanning will not switch on - it detects another anti-virus product.

Windows Defender realtime scanning will not switch on, and the message suggests there is another anti-virus product present but if there is it does show up in Window 10 UI.

The long story is that I am troubleshooting a problem with application software. The manufacturer suggest removing Bitdefender because there product is incompatible. I thought I would give this a try, if only to element Bitdefender as a cause.

Firstly, I upgraded from Bitdefender 2016 to 2017 to see if that made a difference. The application still failed so I decided to try removal.

• I used the standard uninstall to remove Bitdefender 2017, rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I download the uninstall application for Bitdefender 2017, ran it then rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I checked the file system and all Bitdefender files have been deleted.
• I check the registry and found a couple of references to Bitdefender Wallet, then deleted these.
• I rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I reran the uninstall application for Bitdefender 2017 then rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection.
  

I can find no traces of Bitdefender so I wonder why Windows Defender detects another anti-virus software. I've check other posts but couldn't find additional steps for uninstalling an anti-virus software. Any suggestions?

Realtime Protection

When I do Windows Defender update, the realtime protection turns off. Why?

But - - -

It sounds like you possibly have another security program installed or there may be
remnants of such a program you previously used that are still on the computer and are interfering with Windows Defender.

Note the statement "If you want to use Windows Defender Antivirus, uninstall all of your other antivirus programs and Windows Defender Antivirus will automatically turn on. You may be asked to restart your device."

Go to Security and Maintenance, look in 'Security' and see what program is listed under Virus Protection. Windows Defender will not be enabled and functioning properly if there is a program other than Windows Defender listed.

You may want to try the steps recommended in Problems
starting Windows Defender in Windows 8/8.1/10 to include (but not limited to) running SFC, scanning for malware and running the software removal tools for any security software
(AVG, McAfee, Norton, whatever) that may have previously been on the computer (to include a trial version of McAfee or Norton) followed by a reboot? List of

You may prefer to install a third party antimalware program (which should disable Windows Defender) and you’ll no longer be concerned with the various issues that intermittently affect Windows Defender on Win 10.
