WARNING, You have a secdurity problem

Bonjour,
J'ai maintenant un "pop up" qui apparait très régulièrement dans mais barre d'outil an bas de l'écran.
Je ne sait comment m'en débarrasé et il est très agrssant.
Je n'ose l'ouvrir car, de toute facon, il ouvre une fenêtre internet pourt le download d'un programme anti-virus non-solliciter. Bref, je ne sais pas ce que c'est mais je n'en veus pas.
Voici le rapport "HijackThis" tel que je le vois souvent demandé dans les forum.
