Virus infecté par infostealer

bonjour à tous,

ma belle soeur à chopé infostealer, et cela l'empêche de se connecter.
j'ai été dans plusieurs forums et ai vu que HijackThis pouvait m'aider. J'ai le rapport, mais je ne sais pas quoi en faire.
je le met ici, si une âme charitable pouvait me venir en aide ce serait vraiment très sympa.

ps: essayé d'être le plus simple possible, parce que j'ai vraiment du mal...
