My personal recomendation would be Nortan antivirus and internet security pro, which is what I use. We have never had any problems. It even has a neat little feature that traces a hackers ip adress and, if succesful, will give you the adress of the physicla location of the computer. We've actually done this a few times. Also if you are going to use a dsl conection for multiple computers, get a dsl router. Most half way decent routers come with built in firewalls.
