coreServiceShell.exe is constantly reading files in the background causing high CPU activity. There is no scan running at the time. Why is it doing it and  how can I stop this?

Even if I turn off  "Protection" it keeps on doing it.

I tried suspending task but Access Denied.

I am running Windows 10 Pro 64bit latest release 170928-1534

Hello wcameron and welcome to the community! 

The CoreServiceShell.exe is actually the main process of your Trend Micro Security program. If no scan is running at the moment, it is probably the Real Time Scan of the Trend Micro Security Program that scans files and folders downloaded or copied on the computer. It also scans websites as soon as you open them or clicked on a link without triggering it manually. 

If it is causing your computer to work slow, Please try the troubleshooting steps provided on our support page below to solve the issue.
