SlowDownCPU.exe-Virus or Spyware? Plauging friends computer

  1. Hi

    My friend has a computer:

    MSI Gaming Package

    1 GB RAM
    NVIDIA GeForce FX5700 PCI(maybe PCI-E, I dont exaclty know)
    Intel P4 2.8 GHz

    Or at least I think...he says he doesnt know his specs. This is all I could give you. Search MSI for gaming package specs if you need more.

    Now for the real problem. My friend is infected with SlowDownCPU.exe, and it happens all the time at startup. We can end it at startup and it will stay ended, but it annoys him.

    We scanned with AVG, Spybot Search and Destroy, and Ad-Aware SE. We cannot find any problems. He has a wired hi speed network, so I think it could be a worm. How can we fix it?

    Thanks, sw123

    Go HERE and follow the instructions on your friends computer.

    Post a fresh HJT log, only after doing the above. Instructions on where to get HijackThis are in the above instructions.

    Regards Howard :)

    I will try to get an HJT log sometime, but I can't today, plus he's paranoid about his computer because his grandfather runs a small business and if the computer breaks, he will have to pay a tech to fix it. It will be quite hard to convince him, but I will find someway or another to get an HJT log from his computer. Thanks for the instruction Howard. :)

    No problem with the copied and pasted log in this instance.

    As far as I can tell, that HJT log looks clean.

    Regards Howard :)

    I`m not disputing something wrong. I`m just saying whatever it is, isn`t caused by spyware etc.

    SlowDownCPU.exe is neither a virus or spyware. It is in fact a legit MSI application.

    However, since you mentioned slowdowncpu.exe, do the following.

    Boot into safe mode. See how HERE.

    Turn off system restore.(XP/ME only) See how HERE.

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE.

    Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.

    Click on the processes tab and end process for(if there).


    Close task manager.

    Run HJT with no other programmes open. Have HJT fix the following, by placing a tick in the little box next to(if there).

    O4 - HKLM\..\Run: [SlowDownCPU] C:\WINDOWS\INF\MSI\SlowDownCPU\SlowDownCPU.exe

    Click on the fix checked button.

    Close HJT.

    Locate and delete the following bold files and/or directories(if there).


    Reboot into normal mode and turn system restore back on.

    Regards Howard :)

    Actually, thanks for the instructions, but I did this to fix it:

    I clicked start then run

    In box typed C:\WINDOWS\INF\MSI\SlowDownCPU

    then found SlowDownCPU.exe and deleted it. I rebooted computer and started up fine and SlowDownCPU was gone. He was so happy. :)

    Thanks for instructions though guys!

    Thanks, sw123
