Aguardando resposta pois esses virus estão me atrapalhando muito e deixando minha máquina super lenta.

Faça o download do ComboFix

É importante que o salve no seu desktop (ambiente de trabalho)

Feche todas as janelas e programas.
Dê um duplo-clique no combofix.exe, marque 1 e dê o enter.
É um pouco demorado, por favor seja paciente.
Quando a ferramenta terminar de rodar, gerará um log. Poste o arquivo C:\ComboFix.txt.
Faça também um novo log do HijackThis para colocar na sua resposta.

Atenção: Não clique com o mouse enquanto a ferramenta estiver rodando, isso pode fazer com que o PC pare.
