Can you explain to me why the virus keeps coming back? I used ComboFix.

Nothing harmful in the log, please don't try running combofix on your own, too powerful to be used without supervision.

• Open HijackThis
  
• Choose "Do a system scan only"
  
• Check the boxes in front of these lines:
  
  
  O23 - Service: ALYac_PZSrv - Unknown owner - C:\Program.exe (file missing)
  
  
  
• Press "Fix Checked"
  
• Close Hijack This.
  

• Download combofix from here, use the top links - combofix.exe
  
• Double click on ComboFix.exe.
  
• Follow the prompts. NOTE:
  
• ComboFix will check to see if the Microsoft Windows Recovery Console is installed.
  ***It's strongly recommended to have the Recovery Console installed before doing any malware removal.***
  
  **Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will automatically proceed with its scan.
  
  
  
• The Recovery Console provides a recovery/repair mode should a problem occur during a Combofix run.
  
  
  
  
• Allow ComboFix to download the Recovery Console.
  
• Accept the End-User License Agreement.
  
• The Recovery Console will be installed.
  
• You will this next prompt that asks if you want to continue the malware scan, select yes
  
  
  
  
• Allow combofix to run
  
• Post C:\combofix.txt back here.
  
  Note:
  Do not mouseclick combofix's window whilst it's running. That may cause it to stall.
