It seem to be neccessary for playing some famous online games (Battlefield ,Cod 4,and many others) But this program still run after closing the game,it boot when you start your computer. So first,check if you need this program it seem that you can remove it ,but do it at your own risk
Came within my Far Cry 3/Ubisoft folder. Extremely annoying as it runs constantly, and my anti-virus programs constantly flag it, but otherwise seems not to do too much.
Anti-cheat made by Logitech Inc. Starts with Windows automatically, but can be prevented using several different programs, including "msconfig.exe".

Best practices for resolving PnkBstrA issues

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