Fenêtres de pub sur internet.

Bonjour,

depuis quelques semaines j'ai une nouvelle fenêtre de pub qui s'ouvre lorsque je change de page internet 1fois sur 4 environ.
Il n'y a aucun signe de CID (je pense) et les pubs sont de toutes sortes : Alice, Neuf, Cdiscount, sites marchands, de voyages etc ; et les fameux "votre ordinateur est infecté blablabla.."

J'utilise principalement voire tout le temps Firefox.
Je viens de comprendre que mon anti-virus (Avira AntiVir) n'était pas un anti spyware (en fait je viens de comprendre la différence....).
J'ai téléchargé spybot mais l'installation ne fonctionne pas (je suis sur vista).

Je me suis donc résolue à télécharger Hijackthis et à poster le rapport (si c'est bien ça...) dans l'attente d'une âme charitable lol...

Merci !
