    Fake virus scan (Win7 Defender)


    All of a sudden I got a security system alert saying I had problems. It is Win7 Defender and they won't let me do anything with the file extension of .exe. I went to safe mode and can't start any programs at all. I know that Malwarebytes can remove it but I can't download Malwarebytes because it has an .exe file extension. All virus/spyware programs, or any other for that matter, can't be started. As soon as this hoax sees the .exe file, it brings itself up. Anybody got any good ideas? Thankfully I have a separate computer to send this from.

    Welcome dach162,

    I remember using a program called Rkill several years ago to stop this malware that locks up the .exe files

    I have that but since it has a .exe, I can't download it to the computer. (I have in on a flash drive)

    This might help. Download using a clean computer.
    Windows Defender Offline

    Sometimes renaming things like Malwarebytes will get past the infection.
    Malwarbytes #21.exe
    Also try using scans from Safe Mode and Rkill from Safe Mode.

    You can also download it as a .com file to USB & then transfer to the infected computer

    1. Do you want to run or save rkill.com (1.59 MB) from download.bleepingcomputer.com?
    2. download.bleepingcomputer.com/grinler/​rkill.com

    If this didn't have the .exe file it might work but anything (and I mean anything) with a .exe won't work. I can't pick up IE or any other program that has an executable file.

    I agree with Doc Rkill has always worked for me.
    Please read this.

    Thanks for all the quick information. The best answer was changing the .exe to .com and trying that. When I did, it allowed me to install malwarebytes and after scanning with that, it removed all of this foolish fake program. The key here was .com. This win7 defender takes over whenever a .exe is called for. Thanks again.
