This is an extrmemly dangerous program.
I noticed my CPU usage was almost always nearly at 100% so I checked my running processes and I found it. I tried deleting it, but it came back. So I renamed it, stopped the process using task manager, and then deleted it. Deleting it reduced my average CPU usage all the way down to 30% and made my computer a LOT faster. I recommend deleting it as soon as possible.

Warning, This is a TROJAN. I had this on my computer but then removed it. I had a "trojan remover" program that could confirm that this was a trojan.
This is a rogue internet security virus. It runs on start up and can affect other files on your computer ex; firefox, this virus tracks information from internet browsers and is capable of sending passwords, credit card numbers, email addresses, and sites you visited to whoever wrote the virus or third parties. You should remove this immediately.

Best practices for resolving rlvknlg issues

A clean and tidy computer is the key requirement for avoiding problems with rlvknlg. 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 doing a repair of your installation, or in the case of Windows 8, 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 rlvknlg.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.
