problems with trojan and spyware

I have a problem with a trojan - Darksma.x as well as spyware slowing my system down and randomly opening internet explorer/firefox to assorted sites. This happens regardless of wether I am online or not.
Any help anyone can offer would be greatly appreciated.

Attached is my Hijackthis log.

Thanks
