Windows Defender Threat Detection

[EDIT 07/09/25 - 12:02]
Problem resolved with EAAC Update.

After some verification, this is very likely a false positive.
The latest Defender update must have improved their detection system linked to the Vigorf.A trojan, which was referenced in the program in 2016.
For security reasons, the player is waiting for a response from an EA member so that he can confirm whether or not this is a false positive.

-------------
I think it would be best if we looked into this together on Discord, it will be easier, and if we find the problem, a message will then be posted here to help other players who are experiencing the same issue.

This didn't fix it either unfortunately. 

idk, the file isn't alive long enough for me to copy it and submit it to Microsoft either.

Yes, I see, but after thorough analysis, I don't see anything in the latest update that could cause this. So even if we uninstall it, it won't change anything 🤔
Try uninstalling the anti-cheat software using the "EAAntiCheat.Installer" application available here > https://cdn.eaanticheat.ac.ea.com/EAAntiCheat.Installer.exe
Then restart your PC and relaunch the application to reinstall the anti-cheat software.

Not able to uninstall the Definition Update unfortunately, and adding an exclusion for the EAAntiCheat.GameService.exe doesnt seem to be working.

Added both : C:\Program Files\EA\AC\EAAntiCheat.GameService.exe and the dll file.

Even though C:\Program Files\EA\AC\EAAntiCheat.GameService.exe is the only one mentioned in the detection.

Edit: I guess it's because Exclusions don't count for Real Time Protection, only scans.

Thanks for the details.My goal is to fix your problem without compromising your PC's security.
So, first, could you uninstall the latest update, “KB2267602” Once you've uninstalled it, launch your game. If it works without any issues, reinstall the update and create a Windows Defender exclusion for “EAAntiCheat.GameService.exe.”

This test will allow us to see if the problem is caused by the update or not, while maintaining security on your device.

Could be any of these updates:

KB2267602 (Version 1.435.518.0) - 01/09/25

KB2267602 (Version 1.435.530.0) - 02/09/25

KB2267602 (Version 1.435.561.0) - 03/09/25

There hasn't been a Security Update recently, according to Windows update.

Edit: I was looking in the wrong place, there was a Security Intelligence update for Defender on 03/09/25, so yeah the same day I posted the issue.

So this is potentially a false positive. Have you recently performed a Windows security update?

Found it. I didnt know EventViewer gave a LOT more information.

This would also explain why it's happening with BFL too.
