[Arquivado] Navegadores não abrem depois que me conecto a internet

Boa tarde pessoal

Estou com o seguinte prolema. Quando ligo meu computador, ele inicializa normalmente, abro todos os aplicativos normalmente, inclusive os navegadores.

No entanto, quando ligo o modem da Telefonica e efetuo uma conexao, ao tentar abrir os navegadores nada acontece, a ampulheta aparece por um tempo, depois some.

Ao desligar o modem, os navegadores abrem normalmente novamente.

Não tenho a mínima idéia do que pode estar ocorrendo.

Não sei se é necessário um log do HiJack, mas aí vai:
