Re,
Merci pour vos réponses, mais rien n'y fait...
J'ai installé ANTIVIR, puis Avast mais sans résultat : aucun virus ou spy trouvé, et toujours le même problème de redirection.
J'ai lancé un scan avec HiJackThis, qui m'a trouvé un process dangereux : O4 - HKLM\..\Run: [braviax] C:\WINDOWS\system32\braviax.exe, mais impossible de trouver ce "braviax.exe"
Ci-aprés la totalité du scan HiJackThis :
