This morning my windows 10 quit starting programs then I rebooted which took extra time to boot up as if it was installing patches but did not say so. After I logged it Norton showed a new module "nwjs" and did not give me time enough to quarantine it. I found a nw.js on google search but did not understand what it was for. What is it and do I need it? Why did Norton not give me time to quarantine ?
