Audio - LoadType Streaming - Win64 exe recognized as virus

Greetings

We have a unity project in Unity 5.2.2f1,
which has about 2000 audio files,
all set to streaming from memory.

Win64-bit .exe build is ~950Mb in size.

Windows 10 refuses to start the exe and throws the following error:

Operation did not complete successfully because the file contains a virus or potentially unwanted software.

I tried to reproduce this in the separate project,
which had only 1 audio clip set to streaming from memory,
and it worked as usual, it was not recognized as a virus.

The only other option I changed in this version of the build,
is adding the .ogv video file to the player settings under Preloaded Assets.
I also tried to reproduce this in the empty project, but without any success.

We are not using any file IO, networking, nor encryption code in the project.

Do you have any idea why this happens?

Thank you for your time.

@Andrija-Stepic use a better new stable version Unity 5.3.6f1 (64-bit).

First pick the 2000 audio files and put them into a Rar in fast compression (a good origina rar. do not use copy software). This will remove same windows files that can have potentially unwanted software attach to it. For making this work, you must unzip it in another root folder. After that, pick up your project : “the separate project, which had only 1 audio clip set to streaming from memory, and it worked as usual, it was not recognized as a virus.” And import 300 audio files (the unzipped ones) and try to run it, start the exe. Then import the next 300 audio files until you hit with the next problem or not. Open remember to open Unity 64 vr.
