Security Alert Pop-Up

Get numerous security alert pop-up during day requesting "I must restart my computer" Going on for about a week. Have restarted numerous times but Pop-Ups continue. How do I fix?

Be sure you are Restarting. Not Shutdown and startup again if you have the Windows Fast Startup feature enabled. If you use Windows 8/8.1 or 10, there can be an issue with the Windows Fast Startup feature.. See more information here.
