IMHO you have far too many 'protection' programmes running but the ones that you have should not cause any conflict. I would only use AVG (or any free AV), MS Antispy and errrrmmm.... that's all. I would suggest a firewall such as Sygate (also free) although I have not used one for 3 years. A bit of common sense will help as no amount of protection will stop a file that the computer owner has executed, albeit innocently.
I cannot see any advantage in home users paying for any of the so-called protection programmes and there is an awful lot of hype and nonsense talked about computer security.
