Turned on the computer this evening and went to ebay to check auctions I am bidding on. Clicked on "myebay" . Under user name it asked me if I was jlitnar or stradman69. Who is stradman69, and what is he doing on my computer?

I logged in as myself, only to find several items I am watching and bidding on along with several items mixed in of items stradman69 is watching.

To make it worse, it seems he is a private member (whatever that is ) and has only a 70% positive feedback, He had 7 out of 24 feed backs that were negative.

Should I be concerned? By using "contact this member" option I sent him a email asking what he was doing on my ebay on my computer.

Same thing has been happening when my wife logs on to her Yahoo account. Seems other people are logged in, and she has to change to her username each time.

Any clues out there?

Thanks
