Image file execution option being populated automatically RRS feed

  • Question

  • Hello,

    I have a W7 computer where the Image File Execution Options key is being populated automatically for various applications with an entry:

    MitigationOptions  Reg_QWord  0x100 (256)

    Every application that has an entry can't run.

    I'd like to know how to switch this off.

    I thought GFlags might be responsible, so I installed it and run, but can't see anything enabled

    Appreciate suggestions on things to try

    Thanks

    Vaughan

  • Hi Vaughan,

    Execute a full scan in safe mode.

    If no help, use a clean iso to in-place upgrade system.

  • Hello Teemo,

    I don't think this is as a result of a malicious attack

    I was using EMET on this PC previously and I think somehow I've enabled some option which is causing the behaviour

    I have removed EMET but that hasn't resolved, so then I reinstalled GFlags to see if there was something enabled in there

    I'd prefer to avoid rebuilding the computer if possible

    Virus scan comes up clean

    Regards

    Vaughan

  • Hello Teemo,

    I think I may have worked this out.

    If I'm right, as I suspected it was due to my previous testing with EMET

    Thanks for your assistance

    Regards,

    Vaughan
