Problème de rogue: XP Antivirus (et autres ?)

Bonsoir à tous !

Bon, comme le titre l'indique, j'ai un problème avec XPAntivirus qui met les pieds sur la table depuis quelques heures, ainsi qu'un autre truc nommé Fausto.
Ni Avast (bien mis à jour), ni Malwarebytes, ni Trojan Remover n'ont réglé le problème : ils détectent bien, la suppression se passe sans problème, mais ca revient tout le temps.

Je suppose qu'un log vous dira tout ca mieux que moi, donc

Voici ce que me dit Malwarebytes

Malwarebytes' Anti-Malware 1.40
Version de la base de données: 2610
Windows 5.1.2600 Service Pack 2
