Win32/CryptExe

Bonjour!

j'ai fais un scan avec AVG et il me dit que mon ordi est infecté par Win32/CryptExe, j'ai regardé les messages envoyés précecdemment a ce propos, mais je comprends plus ou moins ce qu'il faut faire, est-ce que quelqu'un peu m'expliquer SVP ? J'ai fait un scan avec Hijackthis et voila le log:
