ZeroAccess.inf4 Virus in System32/services.exe

Hello, can any of you help me please?

 

I have a virus on my computer, ZeroAccess.inf4 and it is embedded in System32/services.exe.

 

I have tried all of Nortons tools and none have touched it.

 

If you could help me out i would appreciate it.

 

Cheers.

 

Tony.
