Trojan.Zeroaccess!inf4 requires removal

 

 

Hello.

Could you help  me,please? I have this kind of virus in windows\system32\services.exe,

but don't know how to get rid of it. Manual removal required. But I don't know which of the services.exe is real, and which is virus.

 

Windows 7, 64-bit

 

Will it destroy my documents?

Thank you.
