Nexon Guard

Nexon Guard was added in the 4/21/11 patch. Nexon Guard is believed to be one part of nexon's new anti;cheat software, and it is possible to open it in wordpad and see that it has relations to VeriSign, so it is likely how nexon is reported of a possible hack. It is believed to work in conjunction with Black Cipher. The two seem to work very well, as there has been a significant drop in the number of hackers.
