My father hijacks often my pc when I am not around browsing through the net with firefox. This actually freaks me out because he is the definition of what we say "happy clicker"! So I thought I give Sandboxie a try, but I have some questions. Does it come with a free version? Is it what I am looking for? What are the drawbacks? What is the link for the official site? (don't want to end up with a rogue ) I apreciate any advice on this! Thank you!
