very useful tool, diffrentiates user and system processes, provides description for known processes, doubtful processes can be identified(with no desc) and the location of file that started the process is available too
  Abhay Chopra  
Excellent Replacement for Task Manager. Adds extra functionality and ease in trapping wayward applications
Essential tool for shutting down processes and keeping them closed to remove. Especially new viruses and the like that auto restart when stopped with task manager
Amazing free program for checking what your windows machine is running. Rated 2 instead of 1 because you can damage your own machine by killing the wrong processes if you don't know what you're doing.
Powerful Task Magager like Utility, good for killing viruses currently running in memory

Best practices for resolving procexp issues

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