I had a similar problem after Every Hitman Pro Update, However my scenario was 
 ==> Windows 10 Systems ==> Overall 4000+ Errors ==> Only Restart Event Fixed the error Whenever PC Was Shutdown and Turned Back On==> Error Stayed Back 
 Then Someone was Kind enough to let me know the FAST START UP Option on Windows 10 and How it Conflicted With HITMAN PRO (HitmanPro uses a kernel mode driver) and Fast Startup Puts the PC ON Sleep Mode During Shutdown and not really Reload the OS from Scratch for kernel Drivers to Reload and HMPRO Upgrade to Complete

 I Disabled Fast Startup via GP on Systems and Errors were down to 10% from 70% and they are still going DOWN. 
 
 I Hope This Helps In Case You have a Same problem. 
 
 1. Please RESTART a SYSTEM From Start Menu and Check (Do Not SHUTDOWN & TURN ON) 
 2. Check Sophos HitmanPro Alert install(%windir%\Temp\
