Add extra checks, if any. Add confidence score

If anyone knows of any other ways to identify if a program is being run inside of a virtual machine please let me know.

Furthermore, if anyone has any ideas of how to implement a confidence scoring system, should other methods of detecting if we're in a VM is found, please let me know too. For example, the vendor string check isn't reliable as this can easily be changed, so would have a low confidence score compared to checking the 31st bit of leaf 1 of ecx, which is harder to change.
