Bonjour à tous ! Je vous rappelle ma config : Win XP Pro, LnS 2.05, Norman antivirus à jour. Je viens d'effectuer un petit test "anti-troyen" et le résultat donne ceci : " Results of the test We have scanned your computer' ports used by the most dangerous and widespread trojan horses. Here is the description of possible ports' statuses: "Stealthed"(by a firewall) -Means that your computer is invisible to others on the Internet and protected by a firewall or other similiar software; "Closed" (non-stealthed) - means that this port is closed, but your computer is visible to others on the Internet that can be potentially dangerous; "Open" - Means that this port is ready to establish (or has already established) a connection with remote address. It also means that your computer is vulnerable to attacks and could have been already hacked or infected by a trojan/backdoor; Trojan: Port Status GiFt 123 stealthed Infector 146 stealthed RTB666 623 stealthed Net-Devil 901 stealthed Net-Devil 902 stealthed Net-Devil 903 stealthed Optix 5151 stealthed Subseven 6776 stealthed Theef 7000 stealthed Phoenix II 7410 stealthed Ghost 9696 stealthed GiFt 10100 stealthed Host Control 10528 stealthed Host Control 11051 stealthed NetBus 12345 stealthed NetBus 12346 stealthed BioNet 12348 stealthed BioNet 12349 stealthed Host Control 15094 stealthed NetBus 20034 stealthed MoonPie 25685 stealthed MoonPie 25686 stealthed Subseven 27374 stealthed BO 31337 stealthed Infector 34763 stealthed Infector 35000 stealthed Subseven 1243 closed Duddies Trojan 1560 closed Duddies Trojan 2001 closed Duddies Trojan 2002 closed Theef 2800 closed Theef 3000 closed Theef 3700 closed Infector 17569 closed We have determined there are no open Trojans' ports on your system. But following ports we scanned are non-stealthed: 1243, 1560, 2001, 2002, 2800, 3000, 3700, 17569. Although these ports are non-stealthed, they are not open, so your system is not infected. However, having non-stealthed ports on your system means your computer can be "seen" over the Internet. This makes your system a potential target for remote attacks. " Ma question : que me faut-il faire pour rendre "stealthed" les ports "closed" ? D'avance, merci de votre réponse !
