  • Not really @Ulkoma. The question is different since they were talking about physical keyloggers whereas here the question broader.

I guess it would require too much effort and still you would not be 100% sure.

  • Have a reliable anti malware with the latest update perform a deep scan to look for it.
  • If you are very well experience with the OS' processes, take a look to see if any unknown process is currently running.
  • Check the connected USB devices to the computer. Two keyboards are a indication

What could help you:

  • Use a system virtual keyboard to type in your password.

    A virtual keyboard can still be detected.
