comment analyser LOg Kitjackthis

Depuis quelques temps, en navigant sur Internet, j'ai des messages qui apparaissent tels que "Systemdoctor 2006 - Casino etc". J'utilise pourtant bien un anti-virus (AVAST) et les logiciels suivant : SPYBOT - CCLEANER- REGCLEANER - AD ADWARD et EWIdo. Mais cela revient.

Divers liens sur internet précinisent d'utiliser HIJACKTHIS, ce que je viens de faire . Mais comment interpréter le rapport et surtout comment supprimer les Espions ?

Pour info voici le rapport :
