Virus sur connexion ?

Bonjour,
souvant ma connexion wifi est capricieuse ( obligé de redémarrer le PC pour que ça marche ) ; je pense que cela est dû à un prb de matériel ou de compatibilité ( j'ai une carte PCI Netgear WG311v3 et une Livebox ) mais bon,pour l'instant rien n'est confirmé ...
C'est pour cela que je voudrais être sûr qu'il n'y a pas un virus quelquonque qui pose prb à ce niveau là . Je poste donc le rapport Hijacthis de mon PC : si quelqu'un pouvait l'examiner et me dire si il y a souci quelque part , ça serait super sympa ! :)

merci ...
