Part of program called National Instruments LabView
* Service Locator -- A server used by different NI products, such as the LabVIEW Help, the NI Example Finder, and LabVIEW. This server accepts both local and remote connections. On Windows, this server runs as an operating system service but on all other operating systems, it runs as a VI inside LabVIEW. This server listens on port 3580.

National Instruments produces software such as LabVIEW, and which is far from malicious. They deal with a lot of very computer savvy users, so including malicious programs with their software would be quite detrimental to their business.

The NI Service Locator facilitates communication between National Instruments support programs and services, such as the NI Example Finder and RT Proxy. These programs and services use local dynamic TCP ports to communicate with each other. NI Services Locator manages these dynamic ports. Since the Locator runs as a background service, it requires no user interaction.

Best practices for resolving nisvcloc issues

A clean and tidy computer is the key requirement for avoiding problems with nisvcloc. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the nisvcloc.exe process on your computer, the following programs have proven to be helpful: Security 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. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
