[Arquivado]mstds.exe

walder · Dezembro 8, 2006

O sistema operacional Windows 2000 estava infectado com o malware mstds.exe. Rodei alguns programas para tentar removê-lo, assim como uma limpeza nos registros. Porém ainda não consigo conectar-me com a Internet e o navegador IE6 fica dando refresh tendando acessar a página http://dns404error.htm e na barra de endereço consta res://C:\WINNT\system32\shdoclc.dll/navcancl.htm.

Não consigo localizar mais nada de anormal na máquina.

Segue log do HijackThis:

Já vasculhei por resostas em vários sites e não consegui resolver ainda...

Obrigado pela atenção.

Opa walder,

Baixe o WinsockFix.

Execute o WinsockFix.exe e então clique em Fix.

O procedimento acima deve resolver o problema relativo à falha na conexão.

Bem, agora vamos ao malware...

Levando em consideração que você já possui o Smitfraudfix, faça o seguinte:

1. Desabilite a proteção do seu antivírus (temporariamente);

2. Reinicie em Modo Seguro;

3. Execute o SmitfraudFix dando um duplo clique sobre smitfraudfix.cmd --> escolha a Opção 2;

4. Responda sim (y) à pergunta sobre a limpeza no registro (Do you want to clean the registry?);

5. Aguarde o término do scan e a geração do log;

6. Reinicie em Modo Normal;

7. Reabilite seu antivírus;

8. Poste o log do SmitfraudFix (opção 2) + log HijackThis (gerado em Modo Normal).

Aguardo retorno.

Abraços.

Valeu, Jgarcia!!!!

WOW :joia: A resposta foi muito rápida XD~~

Muitíssimo obrigado. A conexão já está ok (graças ao arquivo que você indicou). Eu tinha pelo menos 2 arquivos na máquina que causaram todo o problema, mtdsm.exe e iptables.exe (esses eu fui removendo na unha mesmo), que provavelmente foram instalados depois do malwarewipe. Mas mesmo depois da remoção deles o problema da conexão persistia.

Aqui está o log do HJT (modo normal):
