PC muito lento... será virus?

[Divvy]

Olá amigos,

Talvez me possam ajudar, o meu computador encontra-se muito lentooooooo e desconfio que seja virus.

O mais estranho é que isto aconteceu desde que fiquei com o dedo na tecla SHIFT durante mais de 8 segundos e activei qualquer coisa no windows. Estranho huh?

Ficou muito lento a partir daí, e ficou ainda pior quando se fez o restant no mesmo dia.

Pelo sim pelo não corri o hjackthis para vos mostrar o log para verem se passa-se alguma coisa de errada:

Log limpo, seu problema não está relacionado a malware.

O mais estranho é que isto aconteceu desde que fiquei com o dedo na tecla SHIFT durante mais de 8 segundos e activei qualquer coisa no windows.

Você ativou um recurso do windows chamado "Teclas de filtragem";

Veja aqui como desativar.
