scanning process for E-trust anti virus
Part of InoculateIt
If you wish to stop this file, to save memory, stop it in "local scanner" under "Scanner - services manager". Closing the realtime monitor in the tray is not enough
Continues to appear and hog systems resources after CA eTrust A/V was uninstalled.

Takes up to 95% of CPU in my laptop. I can't control when it starts, and I can't stop it, due to insufficient privileges. A productivity killer.
Painful load on system
  Warrick Jackson  
Hogging my CPU as well, almost shutting down browsing.
It's a crap piece of work, CA needs a better solution.

Best practices for resolving InoRT issues

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