trojan.pat​chep!sys Help!

I guess I am another in the long line of people who are having issues with this Trojan.  trojan.pat​chep!sys was the name of the threat.  A complete scan failed to remove this issue and the cleaning tool suggested by the Norton site also failed to remove this Trojan.  Can anyone give me some step by step instructions to remove this threat or point me to a set of instructions?  Any help would be great!

 

I am using Window 7 Home Premium 64bit.  I'll be happy to pass on any other system information you might need.  Thanks in advance for your help.
