What is nc.exe?

The genuine nc.exe file is a software component of NetCat Network Control Program by Rodney Beede.
In 1995, someone called "hobbit" created NetCat for Unix and used the name "nc.exe"; Rodney Beede later adapted it to Windows NT (and later), where it needs the Minimalist GNU for Windows (MinGW) for an underlying Unix/Linux platform. It gives network administrators a "Swiss army knife" for testing TCP/IP connections and ports. It can usually be uninstalled by looking for "Network Control" under "Uninstall a Program" in the Control Panel. An early well-known MS-DOS freeware program called "Norton Commander" also existed for managing files. (A modern freeware version is called "winnc.exe".) Because these made "nc.exe" a popular name, it appears to be a popular imitation name for malware. NetCat's bare-metal TCP/IP port-level access is useful for testing a network but opens possibilities for abuse. The NetCat source code is free and widely shared so there are many potential versions and some trigger antivirus warnings, although these may be false.

It's being used for restarting your Router (fritz.box in my case). Tools which do this are usually tools to download from OneClick Hosting pages to avoid a download limit.

Mine came with cryptload,I believe to restart the router.I don't know anything more
  Kostas  
It can be used as a trojan. Unless you are the one that downloaded it, it is being used to connect to a computer and let them run commands on your computer. If you run linux, this came with the OS.

My virus analysation show me a "RemoteAdmin.BX" file.

Netcat is a low-level networking tool used to open ports on the local machine. It can be used to send packets to other machines or it can be abused to open a remote shell on your computer.

Poses as Network Control, it tries to sell fake AV software
   
It comes with "Multi Re-Connector" to re-start the router.

Best practices for resolving nc issues

A clean and tidy computer is the key requirement for avoiding problems with nc. 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. Always remember to perform periodic backups, or at least to set restore points.

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. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the nc.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
