I'm not sure what it is. But a .sys file will represent to driver. But don't know which driver it is. I compared with couple of systems. I have not found this file from below path. C:\Windows\System32 folder. But, this file created an issue to cause BSOD. After removing this file BSOD issue was resolved. Suspect this is an malware.

Best practices for resolving windrvNT issues

A clean and tidy computer is the key requirement for avoiding problems with windrvNT. 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.
