Hi masclez, welcome to DaniWeb :D
You first need to help protect your computer by getting the Windows Updates (not SP2 yet), and do some basic cleanup. Instructions for all of this can be found in the links below (if you need help with any of the instructions, feel free to ask).
When you've finished, close any open browser windows, scan with HijackThis, and post a new log please, and we'll help you clean up anything that's still remaining.
