I prefer ZoneAlarm Security Suite.. it has the firewall, virus scanner, and spyware scanner...

I have a link to them on my web page listed below but I'm not sure how much it sells for anymore (I've upgraded a few times and it costs less to upgrade).

Anti-viruses don't prevent outside intrusion of computers. They just keep viruses at bay. You require a strong firewall to prevent unauthorised access to your computer. I will recommend using Comodo, a free to use fully featured firewall. You can get it from http://www.personalfirewall.comodo.com/
