Early Nortons were total crap i admit but this nortons 360 is good, best way to test your antivirus/spyware is download some key logger trogans, which are harmless just make sure the keylogger isn't for a game you have install on your pc otherwise some chinaman will be logging into your game online
. Place the keyloggers in a folder and run your anti virus a good one will find it straight away.
Nortons 360 found the keyloggers in seconds and offered to delete them same with Nod 32. AVG never found them, Antiviril told me my system was clean lol, Avasti said the same thing, McAfee came up with an error when it found the logger and didn't know what to do with it and Kaspersky was onto it and deleted keyloggers.
Best results were N360, NOD32 & Kaspersky. The rest are rubbish
