Find it. Run task manager [ctrl/alt/del] and check processes. Ending the process will stop the keylogger until you reboot.
A reformat of the hdd can remove it too, this is all if it's software based.
Add another hdd in the case and use it to run your programs after you disconnect the one with the keylogger.
They can still see your activity at the network level, but not the particulars like the passwords.
If it's hardware based the device will be at the back of your computer in line with your keyboard at the USB port.
Unless they have your machine emulated at the network level, but I doubt they are going to that extreme...how many people at your workplace?
You can use the on screen keyboard or copy and paste your passwords, but that is not a sure thing with all keyloggers. Some of them take screenshots and log mouse clicks.
