Spyware??? Sti.trace.log.9

sti.trace.log.9

What is the above. I have a cell phone that gets my email. Sometimes I use one email addy to send myself an important doc to a different email addy. I just did this but first had to save my doc onto the files alloted to me by the university I attend. When I sent the doc from my one email to the other, and I wanted to delete the original from the university computer temporary student storage, I found a page that had sti.trace.log.9 typed on it. It was next to the copy of the sheet that I sent. I have a boyfriend that I have recently discovered his jaded and I sent myself the message that included the “incident” I want to know it sti.trace.log.9 is spyware that sends the message I sent to his computer etc. HELP! HIs computer has Windows XP a refurbished IBM computer and I am on a very secure University Windows OS The email I sent to myself goes to my email addy in my phone and in my public computer Yahoo email setup.
