Depending on the level of analysis you are doing, you should be able to
work around a piece of code detecting VMware sessions pretty easily. You
could NOP out the section, jmp over it, change the information returned,
etc. If it calls a IsVMwarePresent that returns TRUE if its running in a
vmware session, just make it return FALSE.
