nProtect Gameguard, a popular program that prevents hacking in many MMORPGs.
Sadly, it is classed as a rootkit and it is only able to be removed manually. This program is also known to hog memory.
Removing it manually can be very tricky, as you have to play around with the system registry.
Well, i have found an app that works, tested myself to make sure of it
Well, uploaded onto my own webspace so hopefully all you guys can have it.
Works on XP/Vista/2000.
