Hijackthis log (need to remove ad.yieldmanager and atmdt trojans)

hi tech guys,

Newbie here and in desperate need of your help for 2 malacious spyware (ad.yieldmanager and atmdt). I don't know if anymore bugs since I also get a popup from my Sytemac telling me there's a backdoor trojan which they deleted but cannot remove and it keeps coming back after I reboot. I've used Spysweep to clean everything up. Pls see the hijackthis log and advice what I should do. thank you for your help. Also, when I go to my IE browser and click on Tools-->Internet Options and try to change the homepage (to anysite) it always comes back to http://go.microsoft.com/fwlink/?linkid=677 all the time. The other thing is that I can't open any radio stations to listen to Internetradio, it keeps making clicking noises and nothing happens (bugs). Please help!
