combat arm files

After all the thing i haer about noob, i keep founding a folder called BlackCipher is this folder from nexon or noob's? also is it harmful

if its harmful how do i get rid of it i have tryed delete and formatting computer it keeps coming out.

Technically it should be nexon's file, as Black Cipher is their new anti - hacking software. Noob named his hack after it....
If you delete it, then it'll just recreate itself..
Should be safe, but just run a scan on it incase.

It's Nexon don't worry.
