Infecté par un virus... tenace

Bonjour à tous!

Voilà, je viens d'avoir un virus sur mon ordinateur. J'ai réussi à l'enlever avec avast, mais ce matin, quand j'ai rallumé mon ordi, j'ai constaté, à mon grand desespoir, qu'il était toujours présent. Il ralentit énormément le système, il ouvre une fenetre popup pour un site internet Russe.... ça me gène beaucoup!
Je vous place l'hijack this que je viens de faire... Pouvez vous me donner quelques indications?
Merci!!
