    Hi,

    I was developing my own application .NET application with Visual Studio 2008, under Vista 32 bits. Vista has the latest patches and updates, I have an anti-virus with up-to-date virus definitions, etc.

    Everything was working fine. Suddenly, my program stopped to function. When I try to debug it with Visual Studio, Visual Studion itself crashes ! And when I try to start the program by double-clicking on the executable it just dies without any error message. If I inspect the Task Manager, I can see that the process is created for a very small amount of time and then silently dies.

    The name of my program is VMOAuthoring.exe

    Now comes the very very strange issue : I CAN'T EXECUTE ANY PROGRAM WHICH STARTS WITH "VM".

    I can take ANY program. If i just rename it with something that starts with "VM" it just crashes. For example :
    VMfoo.exe ----> crash
    fooVM.exe ---> ok
    Vfoo.exe ---> ok
    fooVMfoo.exe --> ok

    So the problem doesn't come from the executable itself (I mean its code), because even if I take another executable and rename it I get the same problem.

    I have removed the anti-virus and reinstalled it : same problem.
    I have checked the disk for errors ; same problem.
    I have moved the executable to another disk on the same PC : same problem
    I have disabled the firewall (who knows...) : same problem

    Why are the 2 letters "VM" so important in my case ??????

    My guess is that you've aquired malware which tries to prevent itself from running inside a Virtual Machine. This makes it harder on malware analysts and anti-virus companies. It's also possible that malware itself is filtering on those letters because it is itself VM based.
