Har jeg virus?

Hej eksperter.

Min computer er begyndt opføre sig lidt mærkeligt.Pludselig begyndte den at smide rundt med pop-up reklamer, lave startsiden om osv. Jeg har kørt både spybot og Ad-aware, som har fundet en del, men desværre ikke alt. I dag da jeg startede computeren skrev den at den ikke kunne starte pga. en systemfejl, dog startede den normalt op da jeg genstartede??
Håber i kan hjælpe, da jeg skal til skriftlig eksamen på mandag og vil ikke risikere lortet brænder sammen.
Hvis det kan hjælpe har jeg her Hijackthis logfilen.
På forhånd tak for hjælpen.
