Hi, I just have a problem with this-beeing without Firewall- and tell the windows firewall is enough and ok! and also the software doesn't have any password (master password). but I am disagree with this by my old exprience about that a Hacker can access to my computer with many ways you know better, for example open ports of win firewall ( assume I am a simple user), so he or she can get access. then can change setting of my Fsecure app, and so he/she can install every badware or Trojan ,... on my system. and you guess, after afew hours he own my system and my lovely Fsecure can't do anything anymore after this.it's to late. So thell me what should we do? against hackers and beenig safe without strong and reliable firewall?
