Trojan qui revient sans arret...comment faire

Bonjour,
Avast détecte sans arrêt un virus sur mon ordinateur...je supprime sans arret mais malgré tout il revient toujours.
je n'y connais rien du tout en me renseignant un peu j'ai vu que vous demandiez pour commencer d'installer hijack et de copier coller le rapport...
chose faite voici!!! c'est du chinois pour moi... en espérant que vous puissiez m'aider a retrouver un pc plutot sain...merci infiniment par avance de votre aide...
