When I receive an email to my Yahoo.com, can someone program so that he/she can get a copy of the email too?

I have a strong feeling someone is also getting a copy of whatever email I am receiving or sending at my Yahoo.com. How can I make sure what I receive or send is not being forwarded or duplicated to another unauthorized email ?

It is possible to install a keylogger on your harddrive which records everything you are doing on your machine. If you suspect foul play, do a spyware scan! If you don't have a good tool already, get the freeware tool "hijackthis", it quickly scans your computer to find settings that may have been changed by spyware, malware or other unwanted programs. HijackThis creates a report, or log file, with the results of the scan. Check the "overview, FAQ and quick start guide" buttons in the top bar to find out how this tool works.

Then google for "hijackthis forum", click on one of the many links and follow the prompts. Those forums have volunteers who help you to analyze your hijackthis log and get rid of the malware on your computer. Below are a couple of links to such forums:
