BleepingComputer.com: Trojan.Vundo

I have been somehow infected with the Trojan.Vundo virus/malware since about two days ago. I realized that something was wrong when Ad-Aware was repeatedly freezing upon entering the C:\Windows\System32 territory. I then went to Norton's site and downloaded the latest definitions; they have weekly automatic downloads and daily manual downloads. As soon as I updated and restarted, two viruses were found, one of which was removed and the other untouched. Norton cannot delete, quarantine or repair it. I tried using Norton's Trojan.Vundo removal tool, which tells me that no such virus exists on my computer, even though as soon as I enable auto-protection, I get a pop-up saying that a virus has been found. I also have to keep auto-protection disabled or the pop-up, which re-appears as soon as it is closed, will significantly slow down my computer. I tried virus scans, adware scans and Norton's removal tool in and out of safe mode and with system restore off, none of which help me. I even tried the Ewido Security Suite. HijackThis also shows that the virus keeps coming back after I delete it.

Here is a HijackThis log.
