From my experience, I’d recommend Avast! Home Edition. It’s light, fast, seamlessly daily update, no ads, detect most current known virus.
If you prefer a paid or commercial version (normally comes with user support), I’d recommend BitDefender. It’s best value for money, I find it the cheapest for performance and feature for Internet Security Software.
