Eu usei VundoFix no passado. A interface do usuário não é tão boa assim, mas funciona bem.
VundoFix is a freeware removal tool for many of the known variants of Trojan.Vundo, Trojan.Conhook and other similar infections.
I've been working on this tool for nearly 2 years constantly updating and improving the way it detects and removes the vundo infection.
Generally an updated version is released once a week and in some special cases sometimes 2 or 3 times in a week. The tool has had great success removing the infection from over 1 million computers to date and I hope to continue with that same success into the future.
