Security Breach?

I am NOT on a shared computer. I am on my home computer. I have never ever heard of this person. I need to know how to report this. I don't need people telling me that I'm on a shared computer. I am on my home computer in NC. Apparently this guy is from NY judging from his screen name. That IS a breach in security and it needs to be reported. HOW do I report it?

Helen in response to your other question and this one,...

last night as i was logging off and closing down my computer, the message on the screen said.... do you want to close down the computer.. someone else is still using it,, and they will lose their data?

mine is also not a shared computer... only i use it!!!!

also looked at my yahoo profile earlier, and it normally says email neno.... this time my email address was displayed!!!!!

pretty freaked out, i am convinced it has something to do with yahoo.
