Can anyone advise me?

I couldn't log onto my Ebay account this evening, and when I checked my hotmail account, there was some messages from Ebay saying I had changed my password and email account (which I hadn't done). I responded to the emails from Ebay, asking for help but haven't heard back. I also looked through Ebays FAQ on security, but I didn't find what I needed.

I have just changed my hotmail and paypal passwords, and I updated Adaware to find 50! spywares on my computer.

Anyone have any advice for what to do now?
