Kaspersky Internet Security update in mid July 2015 started blocking WmiPrvSE.exe because it is trying to "Read memory from other processes". Seems to happen most frequently when CrashPlan tries to backup files to an external USB drive.
Norton Antivirus.exe is reporting that it is being attacked by WmiPrvSe

W32/Sonebot-B drops a copy of itself to the Windows System32 folder with the filename WMIPRVSE.EXE See also: Link tarence
high cpu utilization occupied
it can run away with cpu (every 5 minutes) and is annoying but not dangerous
It is safe. It is also annoying. Whenever one of my applications starts balking, I pull up Task Manager. One of the processes I often find running is Wmiprvse (the others are Unsecapp and wmi). I shut it down and everything goes back to normal.
Disabled it in Services. No apparent problems without it ever running.

Best practices for resolving WmiPrvSE issues

A clean and tidy computer is the key requirement for avoiding problems with WmiPrvSE. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the WmiPrvSE.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
