This file is weird. Ever since I downloaded Maple Story with this gamegaurd crap, my computer has been going insane. And I don't know how to stop this. It keeps trying to end my AV updater, my mouse goes crazy
nProtect Gameguard & cannot kill this process
Part of NProtect Game Guard used in online Games, Not dangerous by itself but annoying and can cause system lag and instability. Even tried to keep me from connecting to the internet not only with the game but with every process.
npggNT.des is a part of the nProtect GameGuard Anti-cheat engine, designed to guard online games from hacking and cracking tools, mouse/keyboard macro's and client/server harming processes. File is harmless, however, it attaches itself to every running process, including hidden ones, on your system. This said, it has become apparent that nProtect is vulnerable to the "Sony Rootkit" but I currently have no way of confirming this.
it's gameguard - tool used by some MMORPG games to make cheating (like hacks) almost impossible
It's an anti-hacking tool and completely safe

Best practices for resolving npggNT issues

A clean and tidy computer is the key requirement for avoiding problems with npggNT. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
