Pb purityscan.eg qui revient sans arret

Bonjour à tous, j'ai moi aussi un petit pb, j'ai intallé AVG anti spyware et après une analyse complête, il me trouve purityscan.eg. Il me propose de le mettre en quarantaine et après quelques temps, si je refais un scan complét, le pb reviens.

Pour gagner du temps, voici mon log hijackthis :
