Hi Guys

I can't seem to get rid of istsvc.exe even after i fix it in HijackThis. And also, I can't find any information about yonwfqg.exe, so I dare not touch it, but I am asuming its up to no good!

Any help is greatly appreciated. Here is my log file:

Hi Colin, and welcome to Geeks To Go!
  • Please set your system to show
    all files; please see here if you're unsure how to do this.
  • Close all programs leaving only HijackThis running. Place a check mark next to the following, making sure you get them all and not any others by mistake:

    R3 - Default URLSearchHook is missing
    O2 - BHO: (no name) - {00000000-DD60-0064-6EC2-6E0100000000} - (no file)
    O4 - HKLM\..\Run: [NuArCvgkc] G:\WINDOWS\yonwfqg.exe
    O4 - HKLM\..\Run: [GkBxrh2] G:\WINDOWS\yonwfqg.exe
    O4 - HKLM\..\Run: [GkBxrh$v/fG:\Program Files\ISTsvc\istsvc.exe] G:\WINDOWS\yonwfqg.exe
    O4 - HKLM\..\Run: [IST Service] G:\Program Files\ISTsvc\istsvc.exe


    Click on Fix Checked when finished and exit HijackThis.

  • Reboot into Safe Mode: please see here if you are not sure how to do this.


    Using Windows Explorer, locate the following files/folders, and delete them:

    G:\Program Files\ISTsvc\istsvc.exe
    G:\WINDOWS\yonwfqg.exe

    Exit Explorer, and reboot as normal afterwards.



    Post back a fresh HijackThis log and we will take another look.
