QUOTE: A new round of malicious billing spam e-mails were received yesterday. All attachments have the filename of Rechnung.pdf.exe. Two variants emerged from these spams: W32/Nurech.X and W32/Nurech.Y.

Later in the day, the phrase "Love is all Around" was given a new meaning when another batch of Stormy was received. This new Stormy is still adhered to the theme of Love. Filenames of this new variant could be any of the following:

Flash Postcard.exe
Greeting Postcard.exe
Greeting Card.exe
Postcard.exe
flash postcard.exe
