What in the hell is happening with the "dinput8.dll" file ???? Heeeeeelp !

[Nemesys9999]

I'm playing this game for years and never experienced this before.
To be clear, I didn't reinstall anything nor did a "check file integrity".
I just started a new in game profile (I was missing my Twilight Odin ...).
And yesterday, my anti virus (not a free one ...) quarantined a "dinput8.dll" file (threats detected : GenericRXVQ-XT!BD5FCAECF45B) which was located in ...\Steam\steamapps\common\FINAL FANTASY XIII-2\alba_dta\prog\win\bin
I didn't restore it and today, same thing - so something reinstalled the dll file in Steam FFXIII-2.
What in the hell is a Microsoft DirectInput DLL for DirectX 8 process doing there?
It should be in C:\Windows\System32\dinput.dll (and it is !!!).
So I have 2 dinput8.dll files ... (one quarantined)
Does anyone know what's going on?

Some mods will use dll's like this to inject themselves into the game to allow them to work. An example of one of the most well known ones is ReShade.

This does mean that some antivirus programs can pick this up as it can look like unwanted behaviour. For example for this game, older versions of FF13Fix used dinput8.dll in this way (newer ones use a different dll).

Of course, if you are unsure, best to be safe than sorry.

I have no mods installed for FFXIII-2 !
I think I'm gonna choose the safe way ...

As as professional and hobbiest computer scientiest, i can tell you the next

When you develop an app, mostly, you don't do anything at scratch. You use severals layers of development stacks on the IDE, and those are called SDK's, API's and libraries. When I work in a project, I do it for one exact build of those SDK, API's and libraries.

So the most common practice, is to include the library you build with your software to give sure that this will not break with an update. And that's what exactly happening here.

You can delete dinput8.dll included in the game safely, but then Square ENIX don't know if your game will work as intended. (You may benefit even from better performance as this is a updated version)

Anyway, you don't really need to be that concerned about computer security. Your AV is giving you a fake positive based on modified/hacked dinput8.dll maybe used to inject code into your software. And this is not such a bad thing, maybe, Square ENIX had to edit dinput8.dll to fix something on the go.

I played (with the file still quarantined) and the game is working perfectly.
