I have AVAST! Antivirus, a free one. I have discovered right now it has a "silent/game mode" but I guess that's just to not tell you anything while doing stuff. I
think the firewall is deactivated, it's hard to know that in windows 7 though (the configuration isn't as easy to find as XP) I'll take a look at it
@Robert
I'll try Hamachi, now that you say it... I have it gathering dust when it could be useful :|
@JsutAnotherplyrpls
Homestation router, the complicated configuration has a logo of ADB, so I guess it's that.
