trojan.patchep!sys and services.exe virus

Hello,  

 

I've been having an extremely difficult time getting rid of these viruses.  I have Norton Business suite.  Scanning in safe mode allows me to detect the virus, but when Norton cannot delete them.  I have used NPE, MBAM,  Superantispyware and TDSS to no avail.  I have seen people on here with success, so am willing to give it a shot.  

 

Details of the system:

Windows 7 64 bit SP1

 

I do have a flash drive.  And that's all I dared to do for fear of getting chewed out. :D 

Any help would be freatly appreciated.  Thank you !!
