One other thing I thought I would throw out here, if you use a large carrier such as AT&T for your home phone and internet many times they offer anti-virus software free of charge with your services. I use AT&T U-Verse with my home phone and internet bundle and they offer McAfee Security Suite for up to 5 computers free of charge with my service. I did not find this out until after I had already renewed my subscriptions, but this will be good next year when renewal time rolls around.
