Hi, I saw so many posts about Sandboxie, GesWall, DefenseWall,... They are kinda new to me. I've got confused a lot about them. It is my new testing security setup: Layer 1: Comodo 3 (with D+): It is for protecting network hacking (like banking) and early or zero-day attack/malware. Layer 2: GesWall Free: If somehow Layer 1 gets failed and malware gets into my PC, GesWall will isolate and monitor them. Layer 3: Avast Free: If there is something wrong with Layer 2, Avast will take its action and take care of those malware. What do you think about it? Is it good enough? I'm thinking about installing Returnil but I don't know if it's worth to install because it's somewhat similar to sandbox which GesWall is currently handling. Thank you!
