As I have said before, my sister is a network specialist for the State of Texas, and when she sends me an alert, I take it seriously. She often becomes aware of viruses before the protective software post solutions.
Here is a copy of her email:

There is a new High Alert virus that we'd like to warn you about. Please do not open any email which reference
"My Party".

This virus CAN appear in the form of a webpage address. It references photos that can be seen at Yahoo and provides what appears to be a link to Yahoo. The attachment is in actuality an executable file with a .COM extension, not a URL. Running the attachment infects the local machine.
