it starts up every morning when windows enters net,i turn it off in task manager,it stops some programs from working,i believe its microsoft either stealing or ruining programs.
I ran something that I suspected was a virus on a test machine and as it turns out, it is a virus. After I ran it, it disappeared and wmiadap appeared as a new process that I don't recall ever seeing before.
this file "wmiadap" does conneck to the internet via a hacker, it sends and gathers commands from hacker to make changes in your reg. sys.
I attempted to open chrome, but it would not open. I ran Rkill and that process was eliminated, the internet runs great now, a little sketchy but I wouldn't suggest removing it.
this is part of the windows 7 antivirus 2012. use rkill.exe to stop this process

Best practices for resolving WMIADAP issues

A clean and tidy computer is the key requirement for avoiding problems with WMIADAP. 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 doing a repair of your installation, or in the case of Windows 8, 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 WMIADAP.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. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
