Trojan false alert

Hi... sorry if this is in the wrong place

 

I am running W7 with NIS 2012 and Malwarebytes (free version) I ran a full Malwarebytes scan and it found the following 2 files and quarantined them

C:\Windows\System32\DFDWiz.exe (Trojan.FakeAlert) -> Quarantined and deleted successfully. C:\Windows\winsxs\x86_microsoft-windows-d..ostic-user-resolver_31bf3856ad364e35_6.1.7600.16385_none_c50b5b3967029178\DFDWiz.exe (Trojan.FakeAlert) -> Quarantined and deleted successfully

I then ran NIS full scan it found nothing

I then ran Norton power eraser this also found nothing

Any ideas

 

Thanks...
