Hello! Many places have seen the question of why begins to copy itself to "NCLauncher.exe" they could not a solution.
So when you downloaded the launcher installed, the program would start automatically mad he starts to copy the "NCLauncher.exe" in the names:
nc0c7c ~ 1.copy.exe
nc0c7c ~ 2.copy.exe
.
.
.
After 20 minutes, thousands, or even tens of thousands of files are created in this way.
I contacted NCsoft. They did not know what to tell you why this is.
Then it turned out that there is a "cute" virus which in some programs to give the order to copy itself.
Name of the virus Win32: Neshta
Infects everything, but not all of the anti-virus program indicates. I have NOD32 and Norton did not indicate only the Avast.
I hope I helped those who may have problems that were / are at the top.
Sorry for my bad english ...
