I installed Norton Security last week, replacing Norton 360. This is on Win/XP SP3. This machine runs several Servers that receive remote connections. Everything runs slowly now so I am looking at the Windows Task Manager. The CPU is running 80-100% (Intel core2 CPU 4300 1.8 Ghz). The process NS.EXE is constantly using 30+% of the CPU. With no applications running my machine now idles at around 50% CPU. With the Servers up, at times socket connections cannot be made or existing connections are dropped. I have tried turning off all the various parts of Norton Security with no change. When I use Task Manager to kill the ns.exe process the CPU immediately drops to normal levels and everything runs fine but of course I have no security. I don't see this problem on my Win7 machines. Are there any settings that might help me, or am I just going to have to uninstall this thing?
