The Storm Worm has returned with a new incarnation. This one sends you Valentine's Day greetings and has a link for you to download your cute Valentine's Day attachment. The subject lines of these emails are as mushy ones; i.e. Eternity of your love, I love you soo much, Falling in love with you, For you my love, Our journey, Our love nest, Memories of you, and A kiss so gentle.

The mails come with a Pink heart, and typically read: "Your download should begin shortly. If your download does not start in 10-20 seconds, you can click here to launch the download, and then press run. Enjoy!"

On clicking on these messages, a file named withlove.exe or with_love.exe -- carrying malware named 'Zhelatin.sg' -- is downloaded onto your PC.

'Zhelatin.sg' then drops another file named 'burito.ini', stops antivirus from running on the PC, and activates a range of ports to connect to peer-to-peer (P2P) networks. It then starts sending out spam and such other stuff the remote attacker may want to send out from the infected PC.
