That file belongs to your Realtek wireless network adapter drivers.
Reinstall the drivers.
Never get drivers from Windows Update. Get them from:
1. The device mftr.'s website; OR
2. The motherboard mftr.'s website if hardware is onboard; OR
3. The OEM's website for your specific machine if you have an OEM computer
(HP, Dell, Sony, etc.).
Read the installation instructions on the website where you get the drivers.
