After downloading the update on Friday I started having problems with my computer. It came up with a blue screen twice and I uninstalled Norton. I spent the whole day Saturday trying to reinstall and correct the problem. A message box popped up that said C:\programdate\norton\{0c55c096-0f1d-4f28-aaa285ef591126e7}\nis_20.1.1.2\definitions\virusdefs\20121019.022\cceraser.dll I went to support and tried the auto fix and again the blue screen came up that said something has caused windows to shut down. I then uninstalled the program completely and downloaded AVG for now until this problem gets fixed. I would appreciate any help.
