Trojan attacks despite Norton Anti Virus?

I am running Windows XP and have Norton Anti Virus software. It is regularly updated (every week). Recently I ran a full virus scan and 18 virus were isolated on my computer and dealt with. The main culprit was Trojan.ByteVerify. What I don't understand is if I am protected by the Norton Anti Virus & Firewall software, how can these malicious viruses get into my system??

Thanks in anticipation
