For the last couple of years I've been running a layered approach to security. Before that I was an Avira Suite user and before that I recall using Avast Home, ESET Suite or even AVP / Kaspersky. I realized that I was never ever getting malware at all and wanted to control more my security settings and have a leaner system. I tried many programs: antikeyloggers, firewalls, HIPS, SBie... My current setup is: Windows 8 Pro x64 + Win FW + WSAC + WinPatrol + Ad Muncher + Norton DNS + some one demand apps such as Hitman Pro and MBAM. Plus I use FFX with NoScript + RequestPolicy + HTTPS Everywhere. Looking up for a new EMET that officially supports Win8 (current build is buggy in Win8 AFAIK). My system feels light and secure.
