Maybe it was your antivirus, if you have one? Usually, when .exe files disappear on my computer they are deleted by antivirus... I have no idea why computer might consider it a virus, since NWJS is an open-source project, and I used it for portabling the program for Windows. Anyways, if only your nw.exe disappeared, you can download it from here, and try adding it to antivirus' exceptions. And while downloading that .exe just avoid the "Insecure download" message, if it appears.
