[Resolvido] ntcvx32.dll (backdoor.small.52.al) Irremovivel

[JJS 0]

É o seguinte, estes arquivos ntcvx32.dll (backdoor.small.52.al), ntswrl32.dll (backdoor.generic2.slc), e se não me engano tambem um chamado Idapi32.exe, foram detectados tanto pelo avg como pelo avast, todos em C:\WINDOWS\SysWOW64
mas sempre voltam apos religar o micro. Vi alguns post relacionados a eles, mas como estou usando o Xp64 fiquei na duvidade do metodo a usar.

Obs. Não sei se foi coincidência ou não, mas isso aconteceu lo apos eu ter instalado o HLSS (aplicativo usado no Counter Strike), o avg detectou, mas eu ignorei por ser um aplicativo que eu ja utilizo a anos, e nunca tive problemas com ele.

este é o log:

Opa JJS,

 

Baixe o ComboFix em:

ComboFix

 

1) Desabilite o seu anti-vírus temporariamente;

2) Dê um duplo-clique no combofix.exe e tecle "1" para prosseguir. O processo vai durar, em média, 10 minutos;

3) O ComboFix reiniciará o PC automaticamente, a fim de que o processo de remoção seja finalizado (somente se houver infecção);

4) Quando a varredura acabar, será gerado um log, que estará em C:\ComboFix.txt;

5) Não clique na janela do ComboFix, nem feche clicando no X, enquanto a ferramenta estiver sendo executada, pois isto implicará na desconfiguração de seu desktop (ele ficará todo branco);

6) Para parar ou sair do ComboFix, tecle "N";

7) Reabilite o seu anti-vírus;

8) Preciso que você cole o conteúdo do ComboFix.txt em sua próxima resposta.

 

Abraços.

Caso resolvido Jgarcia

 

Notei que o problema era com o csrss.exe, verifiquei no gerenciador de tarefas q alem deste processo ainda entava sendo executado um tal

de csrss32.exe. Verifiquei no log do HijackThis estava aparecendo esta entrada: O4 - HKLM\..\Run: [csrss] C:\WINDOWS\SysWow64\csrss.exe, que na verdade era falsa, finalizei o processo do csrss32.exe, e fiz uma pesquisa no micro procurando por csrss, onde me apareceu um arquivo csrss-exe.pf(ou algo parecido em C:\WINDOWS\SysWow64\) , que tinha cido atualizado a pouco tempo, deletei ele, resetei o micro, fiz um varredura com o AVG e pronto.

 

Obrigado por sua atençao.
