Hi. I'm a novice in this paticular area(security), and I learned English as my second language, so this question might be hard to understand for some of you. Facts: I use Vista. I'm a registered user of ESET NOD32 (expires end of this year, and unable to renew it, because the ESET in my country no longer supports for home users) I use a router (wireless for my laptop i'm using). But the best discovery I made is a program called Sandboxie. I like the idea that it "sandbox" stuffs and it is free. Now here are my questions. 1. Is my security setup "secure" enough? 2. Is there any program that is free and that goes well with Sandboxie?(I think I heard it goes well with Returnil, but I don't have an idea what it is) 3. I use the Vista built-in firewall, is it okay? 4. Can you answer these questions in a very basic English so that I can understand?
