DO NOT OPEN IT.
Evan, you have a virus and you need to get rid of it. Look in your system32 folder and see if you have the file "wingo.exe" If you do, that means you have it and its an email worm. That's how i got an email from you even when you didnt email me.
The virus is a trojan called
I-Worm/Bagle.AZ
i suggest you google it to see how to get rid of it.
