Os sintomas que ocorrem na máquina são 2:

 

- Ao iniciar o PC, o McAfee avisa imediatamente que já uma sobrecarga de buffer no services.exe do Windows.

 

- Ao trabalhar com o PC, ele desliga sem aviso prévio.

 

Isso ocorreu após ele baixar arquivos no Emule, no qual 1 veio infectado.

 

Desconfio do seguinte arquivo: C:\WINDOWS\system32\dumprep.exe. Dou um fix nele? Há mais algo a se fazer?

 

Muito obrigado desde já!

 

Abraços!

Pesquisei sobre o C:\WINDOWS\system32\dumprep.exe e vi que não há nada de errado com ele, já que é o responsável pelo envio de relatórios de erro a Microsoft.Então, o que pode estar causando esse erro?Obrigado desde já,Diogo
