Im with VPN4ALL but a few things concern me, their installer/client app you use to connect to their service comes up as untrusted on Comodo firewall everytime and says it's not digitally signed what ever that means. Is this bad? Could it be a backdoor/Trojan? I also get random connect messages to servers from the client that Comodo picks up even when I'm not connected. Anyone else have experience with VPN4ALL?
