Demande d'analyse d'un log HijackThis

Bonjour,

Je suis victime de la malveillance "ByteVerify Exploit"... En effet, la page d'accueil d'I.E est forcée par défault à http://oqmkzf.t.muxa.cc/%68%2E%70%68%70?%61%69%64=35

J'ai suivi des conseils trouvés sur le Net et ai utilisé le freeware HijackThis dont voici le log :

Merci à quiquonque de m'indiquer ce que je dois supprimer !

En effet, j'ai fait un test en supprimant toutes les lignes comprenant "http://oqmkzf.t.muxa.cc/s.php?aid=35 (obfuscated)" mais ça ne suffit pas pour éradiquer la malveillance.
Quand je redémarre mon ordinateur, l'URL par défaut est à nouveau modifiée....

Merci de votre aide !
Sébastien.
