Help with Vundo Trojan

My computer is infected with the Trojan Vundo virus. I have read every thread on this board and tried the following solutions but have not been able to remove it.

 

I did a full system scan using Norton Internet Security full in Safe Mode. Before I did the scan, I updated the virus definitions and disabled System Restore as Symantec recommends here: http://www.symantec.com/security_response/writeup.jsp?docid=2004-112111-3912-99&tabid=3

 

The scan discovered the Trojan Vundo but could not completely remove it. The scan found over 200 affected registry files but could not delete these.

 

Next, I ran Symantec's Trojan.Vundo Removal Tool 1.5.1. Before I ran the tool, I made sure that the infected PC was not connected to the Internet, as per Symantec's instructions. The tool said it could not find the virus, but the virus is definitely still there as I keep getting popups, etc.

 

I tried running Malwarebytes as some posts recommend but the software would not download on the infected computer. So I downloaded it on a clean PC, saved the file onto a flash drive and then saved it to the infected PC. The Malwarebytes program would not run on the infected PC.

 

Can someone please help?
