OK, I'm looking to tone down my security setup, and ditch Comodo & Defense+. Looking for something simple, effective, and most of all, relatively quiet. Right now I'm using A-Squared antimalware (the free year they gave out last month), but not a fan of it having to run under an admin account. Threatfire has no Vistax64 support, and all they say is "soon". How is DriveSentry these days? Are there any other behavioral HIPS I'm missing?
