Is there something a person could install on your computer that would record your keystrokes and they access it from a different location?
Long story short, I let the boyfriend of one of my friends work on my computer back in the spring - it was running slow and certain programs took forever to open. He removed some programs and installed something called Piriform CCleaner, which I as far as I can tell cleans up my computer when I run it every two weeks.
At a later time he asked me out of the blue, with no reason, whether he "had me down" as using Internet Explorer or Firefox (whatever that other browser name is). I answered IE but when I asked him why he wanted to know he wouldn't give me a response - which has concerned me still to this day, what did he need that information for?
I've now had two situations where I am left questioning whether he has accessed information I put in facebook email and yahoo email to two different friends.
So far I've changed the passwords to both of those accounts, and looked under my control panel to see if there are any programs that look odd to me, but I didn't notice any.
I'm still paranoid though, is it possible that he could have installed something on my computer that is logging my keystrokes, and therefore would know what I changed my passwords to?? If so, any suggestions of what I should look for and where I should look for it on my computer would be greatly appreciated!!
