I once relied on the XP package and ended up with several viruses and a couple of worms. I even had my checking account breached. I destroyed the old hard drive and replaced it with a new one. I also loaded the Norton Fire Wall as well a virus scanner. Not only is my system more secure, I can also trace the origin of any potential intruders, with their country of origin and address(in some cases). The fire wall will give me a warning and allow me to trace the intruder and make a decision on rather to allow the command or block it. With this I can also report potential hackers or intrusions. For me; I love it and the price is completly secondary in comparison to the price I paid for not having it. Best of luck!
