it's installed at %AppData%\Local\Temp\iswizard05\cidaemon.exe Looks like some kind of trojan, I don't know. Looks like it has something to do with BitCoinMiner-CA.

Indexing
   
Occasionally locks folders and makes them unable to delete or rename. Using the SysInternals (now MS) command handle.exe can reveal when the indexing process has latched onto a particular folder.

My systems goes to hang stage , because of cidaemon.exe is showing 43,176 k memory usage and 99 cpu usage in task manager

Cause This issue can occur if the Indexing service is running on the computer. The Indexing service uses the Cidaemon.exe process to index files. The Cidaemon.exe process builds and updates the Index catalog. Additionally, the Cidaemon.exe process typically uses lots of pagefile space and lots of CPU time. Back to the top Give Feedback RESOLUTIONTo resolve the issue, turn off the Indexing service. To turn off the Indexing service, follow these steps: 1.Double-click My Computer, point to Explorer Bar on the View menu, and then click Search. 2.Click Change preferences, and then click Without Indexing Service. 3.Click No, do not enable Indexing Service, and then click OK.

Not dangerous, but it insists on completing its tasks before allowing the computer to download updates - at least on my machine

My CIDEAMON.EXE file runs some times to 100% of CPU. Also, after first time I saw this problem, Some of my processes has not any "User Name" in the "Task Manager". Anyway, After a while I saw some trojans attacks. Finally, they forced me to reboot. After reboot, viruses do not show themselves but I think they Installed and will run as soon as they can.

cidaemon.exe would not let me update adobe reader or download a newer version until I stopped the process.

Best practices for resolving cidaemon issues

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