Need it to be light on resources and effective at keeping my computer safe. Before hand, I used Kaspersky. While it was a good AV for my current computer, I need something just as good as well as less resource intense as Kaspersky is.
Careful they include Chrome with the install, so uncheck that box during the install. Also I would choose the custom route, and don't install any of the tools, just the basic virus scan part, to help keep it light.
