End the trojan blockade

I am constently getting trojens that Norton is blocking.

The files on quarantine log that keep popping up:

 

000000cb.@(Trojan.Gen.2)

00000008.@(Trojan.Gen)

desktop.ini(Trojan.Zeroaccess)

80000000.@(Trojan.Zeroaccess.B)

80000032.@(Backdoor.Trojan)

00000004.@(Trojan.Gen.2)

 

I am running a 32 bit Vista Home Basic, and my security is Norton Internet Security 2012. Please assist. I'm not sure if each of the trojan problems on the board needs a unqiue solution or not.
