Windows 10: Battleye anti-cheat causes windows defender to scan

I've been plagued for some time now by windows defender deciding to go haywire every time Battleye anti-cheat launches. Multiple games such as Rainbow six: siege, Escape from tarkov, DayZ and Arma 3 use this anti-cheat, and when these games launch, the first thing called is the anti-cheat they use. When Battleye launches, windows defender kicks in and does what I can only assume is a system scan, or a scan of Battleye, using 100% CPU resources for approximately 5 minutes.
How can I prevent this from happening? I have Battleye set as an exclusion from defender, along with a few other files I've seen suggested around.

Error 577 for BattlEye anti-cheat

BattlEye anti-cheat works on first boot of Windows 10 install or update. If you restart after the update it has the 577 error again. What changes from first boot to a restart? Error 577 is usually to do with a file being unsigned, but if you enable test
signing BattlEye has a different error saying test signing isn't supported because people use that for hacks. I have the most recent insider build of Windows 10 14361 and I just built this PC yesterday. The game works on my old PC with the same version of
windows. I've tried sfc scan, dism, running as admin, replacing BattlEye files from my other pc and links from people online, I've tried updating all drivers, reinstalling windows, everything.

I posted here to see if anyone has any other way of troubleshooting this issue. I've asked on the game forums and it's always the same answer that doesn't work. It seems to be a hardware or driver issue because my other computer works, but idk what to do
to troubleshoot and find the issue. I'm having small issues with other games like CSGO takes a long time to launch it stays on a black screen for over a minute.

Build is

i5 6600k

EVGA GeForce GTX 970 4GB SC+ GAMING ACX 2.0 04G-P4-2977-KR

Asus Z170-P motherboard

G.SKILL Ripjaws V Series 16GB F4-2400C15D-16GVB

 

How to scan anti-virus with windows Defender?

For windows 10, I would like to know on how to scan anti-virus with windows Defender, when I select a file and right click, there is no anti-virus for scanning for windows defender and how to make windows defender update automatically?

Does anyone have any suggestions?

Thanks in advance for any suggestions

 

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?
