Hi All, Basically I'm trying to work out a security structure that is more proactive than what I have now (Sandboxie Lifetime Licence + ESET SS5) for my Windows 8 Pro x64 PC. I don't mind paying for security software, but I much prefer upfront one off payments for lifetime licenses, I'm not a fan of subscription software. I was hoping someone could provide a rudimentary breakdown of the different 'classes' of security applications (maybe with some examples of the commonly used products in each class) and outline What the classes of software aim to achieve and how to work out what different programs are complimentary to each other and what are likely to conflict. My rough understanding is that these are the 'classes' of proactive security software: Light Virtualisation (Returnil Virtual System, Faronics Deep Freeze, Shadow Defender, Toolwiz Time Freeze) Anti-Executable: (Returnil Virtual System, Faronics Anti-Executable, NoVirusThanks EXE Radar Pro) Policy Restriction: DefenseWall (32-bit), AppGuard (32/64 bit). Sandbox: Sandboxie For instance Sandboxie virtualises the system hardware on a per application and/or per folder path location basis. Do light virtualisation programs do the same, except totally system wide? I'm guessing policy restriction is the same as making your own SRP through windows just with a nicer GUI? Not really sure on what the Anti-Executables do (obviously they stop things launching) but how do they differ from just running your PC with a LUA that propmts for admin rights when a program starts? Which of these programs work well together? Does Sandboxie + Appguard essential equal the level of protection of something like Return Nil, or does it surpass it?
