"taskeng.exe" keeps running since installing CIS


I installed CIS a few weeks ago and since then “taskeng.exe” is always active.
Before installing CIS that process used to (auto-) terminate a short while after reboot.

I’ve disabled “Build Cache Builder”. No items in CIS’s Task Manager.
What can possibly be the cause?

Windows 7, 32-bit.

I’d appreciate your help.

Best regards.
