So, I hacked my step brother's o3DS some time ago. It was in 11.7 Luma version. He didn't know about hacking so he updated it to 11.8. I told him that it was the Luma not been compatible with the 11.8 so I had to update the boot.firm. I took the SD off his 3ds and inserted it in the pc. But everything in the root was .exe. The anti virus popped up and deleted all folders and files. What is going on?
