Serveur en pinging infini à cause de Forge

Bien le bonjour. Je me tourne vers vous car je suis désespéré.
J'aimerai rejoindre un serveur moddé en 1.7.2. Seul problème :
Quand je me met sur ma version Forge, mes serveurs pré-enregistrés dans la page Multijoueur restent en pinging. J'essaye de me connecter au serveur, et un connexion en cours infini persiste.
Je retire Forge et tout marche. Mais il faut Forge pour entrer sur le serveur.
On a pensé que c'était un problème de Java, car j'étais en Java 8. Je suis passé en Java 7 update 71, et ça n'a rien changé.
Ca ne vient pas du serveur, mais de moi. Et sûrement de Forge. Ce n'est ni un problème de mods car ils sont tous compatible, et une incompatibilité de mod n'empêche pas le pinging.

J'ai essayé de changer de version de Forge, redémarrer ma box, redémarrer mon PC, désinstaller minecraft et le réinstaller etc etc..

J'en conclus que le problème vient de Forge. Mais pourquoi ? Et comment le réparer ?

J'ai essayé de lancer une partie solo, mais ça fais crasher mon Minecraft. Voici le crash report :

J'ai essayé en désactivant l'Anti-Virus et le Pare-Feu, mais rien y faire.

 

Je pourrais le réinstaller une fois le problème résolu ?

EDIT : /!\ Le problème Persiste après désinstallation de l'anti-virus et désactivation du Pare-Feu/!\

 

Et bien, il semblerait que je fasse pas parti de la plupart des cas..
Et moi, je sais plus quel Anti-Virus installer de gratuit ! Car j'avais Microsoft Security Essential..

 

Je t'avouerai ne pas avoir trop compris.. Et je ne peux pas jouer à Minecraft. C'ça le truc.

 

Le truc, c'est que TOUT les serveurs restent en Ping.

 

Donc,je supprime le tout premier serveur pré-enregistré ?

Edit : @robin4002 le problème persiste après l'installation d'un nouveau anti-virus.

 

J'ai supprimé tout les serveurs, et ça bug toujours.
