Anticheat / Memory Protection

Require a programmer who can develop a module which would act as an anti-cheat and memory protection for the popular online action series Half Life 2 and all engine mods (Counter-Strike: Source, Team Fortress 2, etc). The module should be able to protect the process memory against injection, as well as determining if the process has been hooked, detect if any memory value has been manipulated as well as displaying all process modules (including modules injected from the kernel level (ring0)). This module should function on Microsoft Windows operating systems from Windows XP through Windows 7, 64 bit and 32 bit.
