Good idea? I want a simple package that will provide a decent degree of security without being too intrusive or tech-heavy. I read this about using IPsec, Win7's built-in firewall, Windows Defender and Microsoft Security Essentials. It sounds like a possible idea. What do people reckon? Otherwise, how about my old XP setup of Online Armor, Avira AntiVir (always on) and SuperAntiSpyware (on demand)?
