Subject: new photos from my party!
Body: Hello!

My party... It was absolutely amazing!
I have attached my web page with new photos!
If you can please make color prints of my photos. Thanks!
Now, if u had something like this, why would u be clicking the attachment?
Anyways, the virus has to be manually executed to infect - just opening the email is insufficient

The attachment name may trick some users into thinking that if they click on the file, they will be taken to a Yahoo website. Certain email clients, especially those that underline the filename, may make this attachment appear more like a URL than the above Microsoft Outlook example which is more clearly distinguishable. The attachment is an executable file with a .COM extension, not a URL. Running the attachment infects the local machine.
