If your computer is accessed by other people (or even if not) you may want to find if somebody tries to steal your private data. One of the most used ways to do this is by installing a keylogger, a software (or even worse hardware) that captures the user's keystrokes (and that means they can see your passwords, credit card data, private conversations, output e-mails...). Here are a few ways you can use to check if a keylogger is installed on your computer:
1. Use up to date anti virus and/or anti spyware software
Typically a good anti virus software will find most of the commercial keyloggers and maybe more. Keep the software up to date and don't forget to enable advanced detection features for best results (for example check "Potentially unwanted applications" in NOD32).
2. Use a special software tool
There are a bunch of anti-keylogger software on the market and you may get better results with those. I recommend you to use them if you think there is a high possibility to have a keylogger installed. For example I found Cyberhawk to be the only software that detected a custom made keylogger. Kasperky does a good job in this area too. Also check anti-spy.info. More examples:

/ / www. lavasoftusa. com/ software/ adaware/
/ / security. kolla. de/
If you are more like an advanced user you can try finding keyloggers by using a few tools like regedit (registry editor) and/or Process Explorer. It will save you some money but it gets harder and harder to find advanced spyware. You can look here or here for more information about using Process Explorer.
You can also try some hot key combination that are used by this kind of software. Examples: Ctrl + Alt + X or Ctrl + Alt + Wondows Key + X
