Virus ( Hijackthis Log ) Download uden grund

Hey eksperter
Jeg har lige et problem som jeg godt vil have jer til at kigge lidt på. Problemer er at jeg heletiden download og uploader noget og jeg har lige geninstalleret mit windows, jeg bruger du-meter til at se at den download men ja fatter ikke lige hvilket program der kan være kørende, eller om det er en slags virus:

Derfor har jeg lige smidt en hijackthis log ind så i måske kan se om der er noget skummelt: Håber i kan hjælpe -
