Norton Internet Security 2012 19.7.0.9 keeps crashing numerous times, even after numerous restarts in Windows 7 Professional SP1 x64. I purchased CyberLink PowerDVD 12 Ultra and NIS isn't giving it access to the internet to check for any updates. Everytime I've tried to get into the Smart Firewall's Settings to give it access NIS completely stops working and Windows shuts it down completely. I restart my pc again and the problem persists. I'm in Windows 8 Consumer Preview x64 as I post this and I have NIS doing a full scan now as I post this.
