Need help removing Trojan.Zeroaccess.B

I am having the same problem as other users removing the Trojan Zeroaccess and Gen 2 virus.  I am using Norton Internet Security 2012, have run LiveUpdate repeatedly, tried the Zeroaccess Removal Tool and ran Norton Power Eraser.  I understand the process/solution is different for each user.  Could someone help me with the steps? I don't want to copy what I've seen in other posts. 

 

Running Windows 7 32-bit operating system.

 

Thanks.
