User Comments

All I did was remove it from my files and then I didn't see it ever again.
Problem for novice users is that we don't know what apps are essential, and what can be removed safely, however after reading the comments here, I have removed rlvknlg.exe, which has resulted in a faster browser, flash runtime and loading, and doesn't appear to hanging as before.
The program wanted to have access for my Skype program. I denied it.
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.

Best practices for resolving rlvknlg issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active rlvknlg process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the rlvknlg.exe on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. 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.
