Bonjour, j'utilise sygate comme firewall, mais depuis quelque temps et je pense suite à un trojan je ne dispose plus du maximum de protection.
En effet j'ai testé mon firewall on line sur le site de Sygate qui me dit que certains ports ne sont que bloqués alors qu'ils devraient ne pas répondre à un scan, je souhaiterai savoir ce que je peux faire pour le reparametrer correctement, car il y a encore peu quand je faisais ce meme test ma sécurité était totale.

Salut TEDDY BEAR et merci pour ton aide, j'ai vérifier ce que tu m'as dit mais que dois je faire ais-je moyen de retrouver l'état précedent à savoir "BLOCKED" afin d'accroitre la sécurité, en effet je ne peux pas juste interdire au port 3319 de communiquer car il s'agit de mozilla firefox, pour l'autre port le 80 c'est plus mysterieux (SYSTEM32/DRIVER/ndisiuo.sys) connait pas.
Qu'en penses tu???
Qu'en penses tu???
Re,
Refait un test pour voire si c'est toujours le port 80 qui est en cause (m'etonnerais) quand a SYSTEM32/DRIVER/ndisiuo.sys doit pas etre en cause because je l'ai aussi (today sur le port 137) et jamais de probleme.

Re pour le moment ne t'inquiete pas :
"un port "closed" (fermé) n'est pas nécessairement une faille de sécurité. Un port fermé ne peut pas être ouvert de l'extérieur mais il trahit quand même ta présence sur Internet."
