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!
