[Resolvido!]Infecção por Trojans

rgdalmoro · Setembro 13, 2007

Pessoal,

Meu AVG 7.5 detecta os trojans Downloader Generic6.AUM e PSW.Banker3.YNP/PSW.Banker4.ARS, mas o mesmo não consegue removê-los.

Segue, para análise, o log do Hijackthis:

Caro Raphael, não estou tendo sucesso em localizar os arquivos via killbox. Acho que o AVG ativo está interferindo. Agora está desativado.

Segue novo log do hijackthis após seguir os passos indicados:
