it sounds like you got keylogged somehow from an ebay phishing scam. Have you gotten any suspicious emails from ebay members wanting to buy an item right away or something to that effect? I have gotten a few and I knew they were fake because 1. I didn't have any ebay auctions and 2. it wasn't on the email that I have registered with ebay. You have to be careful these days about what emails you respond to and what info you give out.
