Hello fr33tux 

Je vais te faire quelques remontées ou il semble que ADWcleaner n’ai pas détectés tous les fichiers netfiler2.sys.

J’ai fait passé à ma helpée un frst search et j’ai obtenu tous les fichiers 

http://www.cjoint.com/c/GDthdTzpYj8

Comme tu peux  le constater sur le rapport, il y a dans la bécane 2 fichiers netfilters2.sys differents car n’ ayant pas pas le même MD5 et cela à cinq endroits différents !!

1 — L’un , en C:\Windows\System32\drivers\netfilter2.sys ) pour les 32 bits

a un MD5= C2F01E084DD48741F1BD5F023881C95A

2 — L’autre à un MD5 de CCC2471F5269B612A0D1349E7DFE437B pour les 64 bits

C:\Windows\System32\drivers\netfilter2.sys

[2016-11-04 13:28][2015-01-14 09:59] 0051904 ____A (Titan ARC Corp.) C2F01E084DD48741F1BD5F023881C95A [Le fichier est signé numériquement]

Ils sont signés et numériquement par un société Titan Arc Corp ayant pignon sur rue ( signé numériquement )

Ils semblent être utilisé par GameFirst IV sous Asus . Il serait installé par ASUS pour les » gamers » 

J’ai fait tester les 2 fichiers  par Virus Total  

C:\Windows\System32\drivers\netfilter2.sys   https://www.virustotal.com/fr/file/f7d9fe205f40952b8876710512594c6755a2a8912cebb15dbe5c83063d8c00a4/analysis/1492590009/

La demandeuse a désinstallé GameFirst IV 

J’ai demandé un nouveau Adwcleaner

http://www.cjoint.com/c/GDtk6CFCmp8

Le service restant, je lui ai fait dégommé dans un script fixlist de FRST
