Another Trojan.gen 2 80000000.@ infection

Hi,

 

Like many others, I'm getting this pop-up every couple of minutes.  I'm running SEP 11.0.7101.1056 on a Windows 7 64-bit machine.  I have tried to remove this using Symantec's ZeroAccess remover and the Symantec Power Eraser - per suggestions on the Symantec site - without any luck.  I see that many on this forum are being helped with this issue and hope that someone can do the same for me.  Exat details from the SEP notifications (there are 2) below.  Thanks in advance for your help.
