I tried to download the Add-On Pack. Now it says I do not have Norton 2008, which I had recently installed it. Now I have opened Pandora's box. Problem after problem. I don't have hours to spend uninstalling and reinstalling everything. Right now I need to redo Windows Installer. I am about to pull my hair out! Would it be better to uninstall Norton and purchase AVG Internet Security. I have 3 months left on my NIS. I upgraded from NIS 2006 and have created numerous problems. Why I have used Norton all these years I don't know. It always takes too much time to install. Suggetions please!
