Here is a list of HP computers that may contain a built-in keylogger
Keylogger, or malicious software that records keystrokes even when the password is not visible. The techniques of masking the field with the slogan will do no good. Keylogger is able to capture anything that will be typed on a hardware or virtual keyboard.

[...] may include a keylogger in the HP Audiodriver Packages Audio Driver or the Conexant High-Definition (HD) Audio Driver version 10.0.931.89 and older.
The author of this information working for Modzero , who deals with security, is not able to clearly determine whether HP knew about the installed spyware, or whether it itself fell victim to a backdoor developed by an external company - in this particular case by Conexant, a supplier of integrated circuits and chips audio that has prepared drivers for laptop motherboards above the HP models indicated.
Thorsten Schroeder, the author of the article explains it in this way:
The installation of the suspicious MicTray64.exe process from Conexant takes place by means of an audio driver that runs after each login. This program monitors all keystrokes made by the user. Through it, it is also possible to mute the microphone, adjust the volume level, or control the LED backlight.
Keystroke monitoring is added by implementing in the controller the ability to call the SetwindowsHookEx function for handling shortcuts / function keys. Keylogging is most likely a programming error in which debugging and logging of the pressed or released special key is enabled.
All operations are saved in the location:
C: \ Users \ Public \ MicTray.log
If the log file does not exist, the keystroke logging can take place in the context of any running process by the logged in user. So, capturing keystrokes can take place for any running program, e.g. LastPass, KeePass, browsers ...
It is recommended to delete the C: \ Users \ Public \ MicTray.log log and C: \ Windows \ System32 \ MicTray.exe executables and C: \ Windows \ System32 \ MicTray64.exe log files or rename them. It can, however, affect the problems in the operation of special keys to handle the sound (mute, adjust the sound level).
At the moment, HP has not yet released an update, and the latest HP Audiodriver Packages / Conexant High-Definition (HD) Audio Driver drivers are from 2015.
