Badly designed program. Overuse of the disk drive. Killing it from the task manager provide relief from deadlocks due to its overuse of resources.
This is not dangerous at all. It is part of the MS System Center Configuration Manager (SCCM) client update agent or the SMS Agent Host. This program is used much like Windows Update or WSUS to keep clients up to date with current Windows patching, security updates and will also coordinate the update of non MS programs like java or adobe flash. It only takes a hardware and software inventory once a day and report to whatever site code it is set for. Once the reporting is done, the system it reported to will tell the agent what it is missing and tell it to download/install the missing programs/patches. The CPU usage is typically only high when it is running its inventory and reporting cycle or downloading needed updates.
it is from microsoft
McAfee's core AV engine
Virsus are rewriting this process, have been for a while. Check the IP addresses it's attempting to access. Common malware site has been seen utlizing this app. Again do not assume this is a system link. Very evil malware is out there.
It forms part of the SCCM client that is used by SCCM to provide information on you device HW/SW.

Best practices for resolving CcmExec issues

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