System Pro virus removal??

My computer is infected with system pro virus, How can I remove it , hopefully for FREE!

Thank you

Note, system is XP not vista

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.
  

This will not install, I get an error message

The application cannot be executed. The file Mcupdui.exe is infected
Do you want to activate your antivirus software now?

Yes No


I have tried clicking yes and no and the super pro screen comes up,

Any other help you can offer?

Thank you

Please download exeHelper from one of the two links.
Link 1
Link 2

• Double-click on exeHelper.com or exeHelper.scr to run the fix.
  
• A black window should pop up, press any key to close once the fix is completed.
  
• Post the contents of log.txt (Will be created in the directory where you ran exeHelper.com)
  

Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).
