I'm much more inclined to use software that works. For anti-virus and internet security I recommend AVG. It doesn't slow down your computer like Norton or McAffee, and there is a free version. The free version works and provides basic computer security for surfing the internet and opening files. The Anti-Virus edition provides more protection, preferential updates compared to the free edition, and an email scanner. AVG Internet Security provides Anti-Virus, Anti-Spyware, Anti-Spam, Firewall and new web protection. It identifies and stops threats before they become a problem. Buy a two year subscription for the price of one year of Norton or McAffee.
