amazon email scam

Hi

I do often browse through Apple Support Communities for help but this is the first time I have asked a question. Apologies if I haven’t explained my question properly.

I received what I now believe is a scam email from “auto-confirm1317@amazon.co.uk” on 27 September, It had a zip file attached. When I clicked on the Zip file it looked like it tried to open up on the bottom of my mac where all my icons are, but it was fast (a split second). I have had the mac for 3 years and always leave it turned on and update when it asks, as this is what I was told when I purchased it. I have mac os x 10.6.8

If I search for order in spotlight this message appears, “order details 10.exe” is a windows application that was attached to a mail message. Are you sure you want to open it?

Mail received this file on 27 September 2013.

I called the apple care and they seem to think all is fine. There seems to be no problems with the computer. However my concern is that I have downloaded some type of virus that can damage my computer, or get all my data/passwords for the sites I use, like Amazon, online banking, etc. Any help on whether or not I may have damaged anything or downloaded any sort of virus would be welcome.

Many thanks
