Un virus mais lequel

Bonjour,

Mon fils m'a installé un truc, mais si le MESSENGER coquin, bref je l'ai désinstaller mais il y a des traces. moralité lorsque je suis sur le net j'ai des fausses annonces d'infection, des pages de pubs qui s'ouvrent etc etc.

Passage par mon antivirus (F-Secure Anti-Virus 7.30) qui ne detecte pas de trace. Si quelqu'un pouvait m'aider.
Puisque certains savent le comprendre (ce qui n'est pas mon cas) voila le rapport Hijack :
