Windows 10: Defender sees powershell file as virus

I had been using powershell script attached with this for quite a long time. Now windows security is deleting that file as virus. Any suggestion what it finds as security threat?
When I try to exclude that file I get msg as below

PowerShell randomly poping-up in tool bar

Hello,

Just to verify, do you have any scheduled tasks that uses Powershell? Scheduled tasks makes Powershell window appear periodically on your computer, therefore we suggest that you check the Task Scheduler. Here are the steps:

• Click on Start.
• In the search bar, type Task Scheduler and click on
  
  Task Scheduler in the results.
• Under Active Tasks, check for any tasks that use Powershell and the scheduled time.

If the issue still persist, we suggest that you run a Windows Defender scan to see if it will pick up any malware that the first scan missed.

Let us know the outcome.

 

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?
