Microsoft get rid of this program stop its malware. You dont care !@!!
You bought a computer that specifically advertises as having premium audio. Nahimic is part of that premium audio. It's part of your computer's audio driver.
Don't blame Microsoft on the fact that it was your choice to buy a computer with premium audio.
Even if you follow the various advices to uninstall Nahimic, the fact that you bought a computer with Nahimic means that your computer will be crippled without Nahimic. Your Realtek Audio Console will not have EQ, loudness equalization, virtual 3D audio, speaker fill... because those functions belong in Nahimic. Uninstalling Nahimic will not bring those functions magically back in the Realtek Audio Console.
