I currently use a suite made by Computer Associates for antivirus/spyware and firewall. It works well, doesn't hog gargantuan amounts of system resources, and has the option of temporarily turning some features off when I need a little extra horsepower. The update process is a snap, and it hasn't crashed my computer once. A couple of downsides might be the learning curve, and the extra amount of processing that has to be done by Internet Explorer after installing the optional website inspector.
