I ran a scan with trend micro's "housecall" and it found a file called KbdStub.EXE to be a trojan horse. It got rid of it, but I had to go into the registry and delete the key. Also, had to go into the startup program and delete it from there too. Some had said it was connected somehow to the keyboard. My keyboard is fine. I know how I got this virus. My husband went to a sight to download movies.(Dumb A**) So, I went into my control panel and clicked on Network & Internet. I then clicked Manage Add Ons. On the left side you will see show: Pull down the arrow and make sure All add-ons shows.
It comes installed with HP Personal Computers. It's part of their package for both 32 and 64 bit operating systems. It's for their Multimedia Keyboards and resides in "C:\Program Files (x86) Hewlett-Packard\KBD;KbdStub.EXE. To delete it off your pc is to fool with the risk of killing off those mulitmedia keys that are present on the multimedia keyboard that came with your HP PC. I for one would not fool with it; why? I use my multi-media keys all the time, I would not want them unstable and/or not working any longer. I would go to the HP website for more info (note, I did not. I checked other websites when I was reviewing start-up progarms this morning)

Nichts gefähliches :P
I just got a message asking if this program can access the internet. Has never happened before so I said no. Keyboard is still working so it must be a trojan or such. My internet disconnected before I could send this and I cannot access Manage Add Ons to change anything!

Best practices for resolving KbdStub issues

A clean and tidy computer is the key requirement for avoiding problems with KbdStub. 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 repairing of your installation or, for Windows 8 and later versions, 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 KbdStub.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.
