I was searching around in regards how to prevent an application from being killed but haven t really found an answer that describes how it works for antivirus applications for example.
What I am looking forward to do is a tool (similar to Gameguard, xTrap) to prevent cheating on my a simple online game I made on XNA.
In the process of doing features to prevent the user to cheat on my game I was wondering how AVG, Norton and others antivirus application work in harmony with the OS not allowing admin users to close their application but yet shutting down gracefully ?
With out using a second application to watch my anticheat application is it possible to catch kill events on it so I can atleast close my game when that happens ?
I was also considering using my game as a watcher for my anticheat and viceversa to whenever 1 of them goes off the other goes as well but I would like to understand the above as well.
From what I have seen people easyly bypass these kinda of things with simple detours on those calls so maybe having my game as watcher for the anticheater wouldn t be so efficient either ...
Would love some answers, advices, piece of codes related to what I could improve as security for my game and anticheat application.
Also information preventing debuggers such as olly and the such to attach to it.
