Virus!!! I know it is

Hello,
There is a difficulty on my computer. I need help!!! I have a virus that I think will ruin me if I don't get rid of it. My desktop wall paper is gone, my outlook has crashed, and the computer generally has an erratic behaviour. I can hear the processor chatting away while I try to work. Below is my hijackthis log.
