I just bought a brand new Dell. I activated the NIS and then began installing a variety of new programs. I installed a Logitech webcam which required that I turn off my virus protection and my firewall. I did and then installed the webcam. I tried to open the NIS program to turn everything back on and I can’t open the program. I restarted the computer. Nothing. I unplugged the webcam. Nothing. I restarted again. Nothing. Now all my protection is turned off and I can’t do anything to turn it back on.
