Someone may have figured out a way to install a keystroke logger on your computer. It only takes about ten minutes to download and install, and there is nothing to tell the computer user there is anything amiss.

With a keystroke logger, the other person can remotely view EVERY single letter and word you type, and it does screen captures of every webpage you visit, it also collects all your passwords as you use them.

If this is what has happened you will need a professional to find and remove it. Make sure you don't utilize the same computer person you used last time, as that could be the person who installed it in the first place. Or it could be an old boyfriend. Or jealous housekeeper or former psycho roommate.
