I can't decide on what Anti-Virus/Security Solution to pick for an upcoming build I will do. The choices I can't decide from are Norton Anti-Virus 2012, ESET Smart Security v.5, or McAfee Internet Security 2012... I want something that works in the background and doesnt interfere with performance (in the "cloud"), and has excellent security. Thanks for the help! Also name any other security option that is great as well!
