Since I'm the "iracez28" mentioned above, I'll comment:
By now, you know the virus spoofs usernames. If you CAREFULLY view the headers on an infected email, you'll notice the "from" would be me (for example) and the actual sender (reply-to) address is the actual infected person. If you casually look at the email, it's "from me" because the virus attached my email address taken from the infected users address book and stuck it there. This is what makes this virus a major PITA.
Also, you can tell an email is a virus by the attachment and/or subjet.
I can assure you that I would never send anyone an email with a subject of
"Me love you long time - GI" along with an executable attachment. If you get anything like this - delete it.
Anything that can be run: exe, bat, com, scr, etc.... don't open that at all. Regardless of who it's from.

My mother-in-law just got a new computer and she's already on these email joke passing around things. She sent me (my wife) "Christmascard.exe". I told her we deleted it without looking at it and gave her a pep-talk. I'm sure the thing was harmless and cute, but I don't need to find out the hard way.
