I installed Norton 360 and also ran my windows update last week and then shut down my computer. When I put my password in the next day it wouldn't work. I noticed after a couple times that all of my keys were in different places. Like the D key when hit is actually the E key and the S ket is the period. All of the keys are in the wrong places and I can't figure out how to fix it. I have tried a new keyboard, same issue. I have resorted to using the onscreen keyboard under accessibility just to function. I have reinstalled windows, I have uninstalled Norton 360 and scanned for viruses.... Any ideas??
