Windows 10: My Windows defender's ''start actions'' button wont work when a virus is detected. Please...

My Windows defender's ''start actions'' button wont work when a virus is detected. Please help how can I fix this?

Windows Defender "Start Actions" Button Not Working

Windows Defender is telling me "Virus & threat protection. Threats found. Start the recommended actions." There is a button below, which says "Start actions". Clicking this button has no effect. Should I just ignore it?

I'm on Windows 10 Pro, version 1703.

 

Virus Not Detected By Windows Defender

Hi,

If your running two antivirus at the same time and Windows Defender did not detect the virus, We suggest that you remove the virus with the third party malware that you're currently using. We recommend to use a single anti virus. and keep it up-to-date.

Let us know if you need further assistance.

 

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?
