Trojan Virus not supported by Norton?

I ran the Complete Scan and got a high risk from a trojan virus that stated I needed help from Symantec to fix....so I clicked on the link and it says that the page for this is not found.  I also did the search and it did not come up...the Norton Virus calls it:

 

trojan.zeroaccess!kmem

 

Could I please get help on resolving this issue?

 

Thanks
