Query: Takes over your machine when you turn it on

If you don't leave your PC turned on continuously, look elsewhere. Every time you turn your PC on, several of Norton 360's applications start to run and virtually use a majority of your CPU resources. Programs with names like CCApp.exe, LUCom~.exe, LUComServer.exe will keep you from using your PC for the first 15 minutes or so. If you try to use it while 360 is doing it's thing you will find your program will run at a snail's pace. I'm looking elsewhere for my next years AV protection. After several years of Norton products, I have to say this will be my last. No more Norton for me.
