Trojan.zeroaccess!inF4 removal. Please help

Hello, can anyone PLEASE help me remove this Trojan zeroaccess from my laptop? I have had it for 2 days now and Norton cannot remove it or quarintine it. I have been attacked so many times from this trojan and it has been blocked many times, as I am typing this right now I am getting pop up message of it being blocked and needing a restart, I've done that a countless times to no avail.

 

I located where the trojan was coming from and Norton showed me it was in Windows > System32 > services. I tried to delete it myself becuase Norton asks for a manual removal but I'm not able to delete services.
