[Arquivado] Win32: RustNT [Rtk] (rootkit)

Primeiro gostaria dizer que ser for possível me abster de utilizar programas com hijackthis, combofix e bankfix eu agradeceria, porque tive um pequeno problema com um desses programas. Segundo gostaria de saber se é possível eliminar esse rootkit sem a necessidade de formatar o computador. Informações sobre este Malware são bem vindas.

Desde já obrigada!
