Failed Attempt at removing Trojan Mapper. HELP!

Hi
About 10 days ago my internet became noticeably slower and has in that time period ground to a complete halt. I subscribe to McAffe and Adaware and have also used Hijack this which has been really useful in the past. On running these programs I was told that I have attracted a Win32.TrojanPWS.Mapper which I have made attempts to remove.
I have subsequently followed your Malware Removal Guide step by step (apart form the following) :
1. Spybot S&D allowed me to scan but would not allow me to remove the affected files unless I logged on as an administrator. Which I did. IT subsequently took 3 scans. I also had to attempt to install it 4 times as it kept timing out.
2. I Didn’t do the last part of the MG Tools instructions from locating GetLogs.bat

On reboot everything worked fine and internet was running fine. However the following morning it had reverted to how it was before.

I decided to run all the steps on the Malware removal guide again but it has proved futile and having run Adaware again found I still have the Trojan. I have attached 3 of the logs on this message and am attempting teh MG Tools log but it is a zipped file on next message. Can you advise me????? I would be really grateful! Thanks
