Hidden Process Finder is a small software utility that can help in detecting hidden processes.

With this tool you’ll be able to identify hidden processes (rootkits) in your system. As you might know, many stealth malware are known to hide their malicious processes and you don't ever see them making malware removal impossible.

This tool can identify the processes that can’t be found by Task Manager or by other security tools. Hidden Process Finder also lists processes with the hidden (+h) file attribute for security reasons.

As with any tool like this it should be considered for advanced users or techs.
