"Trojan horse Agent2.HXD" infecting the userinit.exe

Hello everybody,

First of all, I am not an expert in computers so I need a very clear instructions (thanks for that). Ok, my problem is that my AVG antivirus has detected in the "C:\WINDOWS\system32\userinit.exe" a "Trojan horse Agent2.HXD" which is considered as: "Object is white-listed (critical/system file that should not be removed)". So, when I start my PC after introducing the username, I only can see the wallpaper: Not folders and not toolbar.

What can I do??

Waiting the answer,

Thanks a lot.

Please download the current version of HijackThis from HERE

• Double click and run the installer.
  
• It will install to C:\Program Files\Trend Micro\HijackThis\hijackthis.exe
  
• After installing, you should get the user agreement, press accept and Hijack This will run.
  
• Select Do a system scan and save a log file. This will open a notepad file of everything Hijack This found, copy and paste it back here.
