[Resolvido!]Trojan Horse psw.banker3.ndf

jaspion · Junho 1, 2007

Olá,

estou tentando remover um cavalo de tróia do computador de um amigo e preciso de ajuda. Ele foi infectado depois que clicou em um link do tipo: "olha que interessante o que encontrei!".

Passei o AVG e ele encontrou o trojan horse psw.banker3.ndf e aparentemente, ele foi removido. Mas sempre que o computador é ligado, o IE é aberto com a página do google e com a barra de ferramentas bloqueada (desativada). Passo o AVG novamente e ele não é encontrado. Se fechar o IE e abrir novamente, tudo funciona normalmente.

Numa das tentativas de pegar o trojan, o AVG localizou-o de novo e removeu, mas o problema do IE continua. Por isso, acho que o trojan continua lá.

Depois de ler outros tópicos deste fórum, eu me adiantei e executei o Hijackthis. Estou enviando o log pra sua análise.

Opa jaspion,

1. Baixe o BankerFix.

2. Desative o seu anti-vírus temporariamente.

3. Dê um duplo-clique sobre o bankerfix.exe. Uma mensagem aparecerá avisando que o mesmo será baixado via internet. Clique em Ok -> Ok. Aperte Enter e aguarde o término do scan.

4. Terminado o scan, leia a mensagem na tela e aperte Enter novamente.

5. Habilite o seu anti-vírus.

6. Retorne com um novo log do HijackThis, juntamente com o relatorio.txt do BankerFix (ele estará em C:\LinhaDefensiva\).

Abraços.
