The virus is embedded in an email that appears to be a response to a craigslist advertisement.
The email containing the virus includes the subject line, “Re: Car For Sale on craigslist.” The email content suggests that the user requested pictures for a car being sold on craigslist and invites the recipient to view the images in a Picasa album. Clicking on the link to the album installs a virus.
I have seen over 1.2 mil emails sent out from this virus from less then 5 computer at one business. This type of virus will spreed from computer to computer very quickly.
