There are two new changes I plan to make to the secure source file.

First is the addition of a try-catch block around realmain. This will allow the program to terminate unexpectedly, and still safely clean up after itself.

The second is to prevent the executable running again, since it can't be deleted without external influences. This will be implemented by a piece of code which checks for the existence of the secure.hpp file, and return immediately if it's not found. Granted, this type of check is easy to fool, but would be better than nothing.
