i dont know if it actually works or not, but EVERY time i start wow (or minimize and maximize it) i get the following messages:
wow.exe was blocked from accessing physical memory
wow.exe was blocked from reading c.exe (my cheat engine)
wow.exe was blocked from reading nlsvc.exe (net limiter)
and i have never been banned for using any of the above programs, including: cheat engine, net limiter, model edit fix, pirox, xyz (awws z plane teleport hack), wow emu hacker, wallclimb trainers, and WPE pro.
using all those for 6-12 months and never a single ban
i for one will always use process guard just in case
