Ayuda por favor problemas raros con Windows 7

Hola,
Bueno mi problema es que mi 7 esta muy raro, no puedo activar el firewall de windows, tampoco puedo borrar algo para que quede en la papelera por que esta dañada, lo tengo que borrar directo(Mayus + Supr), el Internet Explorer no habre y firefox se pone lento al reproducir videos, no hace mucho que me esta pasando esto, aproximadamente unos 3 dias.
Pero no vengo a pedir ayuda asi nomas aqui les pongo un log de hijackthis, ademas ya pase el avast en busqueda profunda y no detecto nada
