[Arquivado]Virus: Trojan - !

yurialbert · Julho 9, 2007

EU não sei como peguei o virus, mas o Avast apontou varios arquivos infectados:

Svchost.exe

windows.exe

wsock32.dll

Com isso começou a aparecer aquela FAMOSA Tela Azul, reiniciar sozinho, programas como Msn e Firefox apresentando aqueles erros de "precisa ser fechado, enviar relatorio".

Os virus apontados são: Win32: Trojan-gen e Win32:Banker-YW [Trj].

To com o Cd do Win XP, é bom eu reinstalar? Eu posso reinstalar sem perder alguns arquivos?

Usei o Hijackthis e o Log deu isso:

alguém?

jgarcia · Julho 9, 2007

Opa yurialbert,

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\).

7. Depois de postar a sua resposta você poderá deletar a pasta LinhaDefensiva contida no C.

Abraços.

PS.: Sugiro que leia as Regras da Seção.
